Introduction
Need to find if a user viewed a specific document or purged an item from their mailbox? If so, you can use the Office 365 Security & Compliance Center to search the unified audit log to view user and administrator activity in your Office 365 organization. Why a unified audit log? Because you can search for the following types of user and admin activity in Office 365:
User activity in SharePoint Online and OneDrive for Business
User activity in Exchange Online (Exchange mailbox audit logging)
Important
Mailbox audit logging must be turned on for each user mailbox before user activity in Exchange Online will be logged. For more information, see Enable mailbox auditing in Office 365.
Admin activity in SharePoint Online
Admin activity in Azure Active Directory (the directory service for Office 365)
Admin activity in Exchange Online (Exchange admin audit logging)
User and admin activity in Sway
eDiscovery activities in the security and compliance center
User and admin activity in Power BI
User and admin activity in Microsoft Teams
User and admin activity in Dynamics 365
User and admin activity in Yammer
User and admin activity in Microsoft Flow
User and admin activity in Microsoft Stream
Analyst and admin activity in Microsoft Workplace Analytics
User and admin activity in Microsoft PowerApps
Before you begin
Be sure to read the following items before you start searching the Office 365 audit log.
You (or another admin) must first turn on audit logging before you can start searching the Office 365 audit log. To turn it on, just click Start recording user and admin activity on the Audit log search page in the Security & Compliance Center. (If you don't see this link, auditing has already been turned on for your organization.) After you turn it on, a message is displayed that says the audit log is being prepared and that you can run a search in a couple of hours after the preparation is complete. You only have to do this once.
Note
We're in the process of turning on auditing by default. Until then, you can turn it on as previously described.
You have to be assigned the View-Only Audit Logs or Audit Logs role in Exchange Online to search the Office 365 audit log. By default, these roles are assigned to the Compliance Management and Organization Management role groups on the Permissions page in the Exchange admin center. Note that global administrators in Office 365 and Microsoft 365 are automatically added as members of the Organization Management role group in Exchange Online. To give a user the ability to search the Office 365 audit log with the minimum level of privileges, you can create a custom role group in Exchange Online, add the View-Only Audit Logs or Audit Logs role, and then add the user as a member of the new role group. For more information, see Manage role groups in Exchange Online.
Important
If you assign a user the View-Only Audit Logs or Audit Logs role on the Permissions page in the Security & Compliance Center, they won't be able to search the Office 365 audit log. You have to assign the permissions in Exchange Online. This is because the underlying cmdlet used to search the audit log is an Exchange Online cmdlet.
When an audited activity is performed by a user or admin, an audit record is generated and stored in the Office 365 audit log for your organization. The length of time that an audit record is retained (and searchable in the audit log) depends on your Office 365 subscription, and specifically the type of the license that is assigned to a specific user.
Office 365 E3 - Audit records are retained for 90 days. That means you can search the audit log for activities that were performed within the last 90 days.
Office 365 E5 - Audit records are also retained for 90 days. Retaining audit records for one year may eventually be available for E5 users and users with an E3 license and an Office 365 Advanced Compliance add-on license.
Note
The private preview program for the one-year retention period for audit records for E5 organizations (or for users in E3 organizations that have Advanced Compliance add-on licenses) is closed to new enrollment. This article will be updated when the one-year retention period is available in public preview or released for general availability.
If you want to turn off audit log search in Office 365 for your organization, you can run the following command in remote PowerShell connected to your Exchange Online organization:
Set-AdminAuditLogConfig -UnifiedAuditLogIngestionEnabled $falseTo turn on audit search again, you can run the following command in Exchange Online PowerShell:
Set-AdminAuditLogConfig -UnifiedAuditLogIngestionEnabled $trueFor more information, see Turn off audit log search in Office 365.
As previously stated, the underlying cmdlet used to search the audit log is an Exchange Online cmdlet, which is Search-UnifiedAuditLog. That means you can use this cmdlet to search the Office 365 audit log instead of using the Audit log search page in the Security & Compliance Center. You have to run this cmdlet in remote PowerShell connected to your Exchange Online organization. For more information, see Search-UnifiedAuditLog.
If you want to programmatically download data from the Office 365 audit log, we recommend that you use the Office 365 Management Activity API instead of using a PowerShell script. The Office 365 Management Activity API is a REST web service that you can use to develop operations, security, and compliance monitoring solutions for your organization. For more information, see Office 365 Management Activity API reference.
It can take up to 30 minutes or up to 24 hours after an event occurs for the corresponding audit log entry to be displayed in the search results. The following table shows the time it takes for the different services in Office 365.
Office 365 service 30 minutes 24 hours Advanced Threat Protection and Threat Intelligence 
Azure Active Directory (user login events) Azure Active Directory (admin events) Data Loss Prevention Dynamics 365 CRM eDiscovery Exchange Online Microsoft Flow Microsoft Forms Microsoft Project Microsoft Stream Microsoft Teams Power BI Security & Compliance Center SharePoint Online and OneDrive for Business Sway Workplace Analytics Yammer Azure Active Directory (Azure AD) is the directory service for Office 365. The unified audit log contains user, group, application, domain, and directory activities performed in the Microsoft 365 admin center or in the in Azure management portal. For a complete list of Azure AD events, see Azure Active Directory Audit Report Events.
Exchange Online audit logs consist of two types of events: Exchange admin events (actions taken by administrators) and mailbox events (actions taken by users on mailboxes). Note that mailbox auditing isn't enabled by default. It must be enable for each user mailbox before mailbox events can be searched for in the Office 365 audit log. For more information about mailbox auditing and the mailbox auditing actions that are logged, see Enable mailbox auditing in Office 365.
Audit logging for Power BI isn't enabled by default. To search for Power BI activities in the Office 365 audit log, you have to enable auditing in the Power BI admin portal. For instructions, see the "Audit logs" section in Power BI admin portal.
Search the audit log
Here's the process for searching the audit log in Office 365.
Step 1: Run an audit log search
Step 2: View the search results
Step 3: Filter the search results
Step 4: Export the search results to a file
Step 1: Run an audit log search
Go to https://protection.office.com.
Tip
Use a private browsing session (not a regular session) to access the Security & Compliance Center because this will prevent the credential that you are currently logged on with from being used. To open an InPrivate Browsing session in Internet Explorer or Microsoft Edge, just press CTRL+SHIFT+P. To open a private browsing session in Google Chrome (called an incognito window), press CTRL+SHIFT+N.
Sign in to Office 365 using your work or school account.
In the left pane of the Security & Compliance Center, click Search, and then click Audit log search.
The Audit log search page is displayed.
Note
You have to first turn on audit logging before you can run an audit log search. If the Start recording user and admin activity link is displayed, click it to turn on auditing. If you don't see this link, auditing has already been turned on for your organization.
Configure the following search criteria:
a. Activities Click the drop-down list to display the activities that you can search for. User and admin activities are organized in to groups of related activities. You can select specific activities or you can click the activity group name to select all activities in the group. You can also click a selected activity to clear the selection. After you run the search, only the audit log entries for the selected activities are displayed. Selecting Show results for all activities will display results for all activities performed by the selected user or group of users.
Over 100 user and admin activities are logged in the Office 365 audit log. Click the Audited activities tab at the topic of this article to see the descriptions of every activity in each of the different Office 365 services.
b. Start date and End date The last seven days are selected by default. Select a date and time range to display the events that occurred within that period. The date and time are presented in Coordinated Universal Time (UTC) format. The maximum date range that you can specify is 90 days. An error is displayed if the selected date range is greater than 90 days.
Tip
If you're using the maximum date range of 90 days, select the current time for the Start date. Otherwise, you'll receive an error saying that the start date is earlier than the end date. If you've turned on auditing within the last 90 days, the maximum date range can't start before the date that auditing was turned on.
c. Users Click in this box and then select one or more users to display search results for. The audit log entries for the selected activity performed by the users you select in this box are displayed in the list of results. Leave this box blank to return entries for all users (and service accounts) in your organization.
d. File, folder, or site Type some or all of a file or folder name to search for activity related to the file of folder that contains the specified keyword. You can also specify a URL of a file or folder. If you use a URL, be sure the type the full URL path or if you just type a portion of the URL, don't include any special characters or spaces.
Leave this box blank to return entries for all files and folders in your organization.
Tip
If you're looking for all activities related to a site, add the wildcard symbol (*) after the URL to return all entries for that site; for example, "https://contoso-my.sharepoint.com/personal/*".
Click Search to run the search using your search criteria.
The search results are loaded, and after a few moments they are displayed under Results. When the search is finished, the number of results found is displayed. Note that a maximum of 5,000 events will be displayed in the Results pane in increments of 150 events; if more than 5,000 events meet the search criteria, the most recent 5,000 events are displayed.
Tips for searching the audit log
You can select specific activities to search for by clicking on the activity name. Or you can search for all activities in a group (such as File and folder activities) by clicking on the group name. If an activity is selected, you can click it to cancel the selection. You can also use the search box to display the activities that contain the keyword that you type.
You have to select Show results for all activities in the Activities list to display events from the Exchange admin audit log. Events from this audit log display a cmdlet name (for example, Set-Mailbox ) in the Activity column in the results. For more information, click the Audited activities tab in this topic and then click Exchange admin activities.
Similarly, there are some auditing activities that don't have a corresponding item in the Activities list. If you know the name of the operation for these activities, you can search for all activities, then filter the results by typing the name of the operation in the box for the Activity column. See Step 3: Filter the search results for more information about filtering the results.
Click Clear to clear the current search criteria. The date range returns to the default of the last seven days. You can also click Clear all to show results for all activities to cancel all selected activities.
If 5,000 results are found, you can probably assume there are more than 5,000 events that met the search criteria. You can either refine the search criteria and rerun the search to return fewer results, or you can export all of the search results by selecting Export results > Download all results.
Step 2: View the search results
The results of an audit log search are displayed under Results on the Audit log search page. As previously stated a maximum of 5,000 (newest) events are displayed in increments of 150 events. To display more events you can use the scroll bar in the Results pane or you can press Shift + End to display the next 150 events.
The results contain the following information about each event returned by the search.
Date: The date and time (in UTC format) when the event occurred.
IP address: The IP address of the device that was used when the activity was logged. The IP address is displayed in either an IPv4 or IPv6 address format.
User: The user (or service account) who performed the action that triggered the event.
Activity: The activity performed by the user. This value corresponds to the activities that you selected in the Activities drop down list. For an event from the Exchange admin audit log, the value in this column is an Exchange cmdlet.
Item: The object that was created or modified as a result of the corresponding activity. For example, the file that was viewed or modified or the user account that was updated. Not all activities have a value in this column.
Detail: Additional detail about an activity. Again, not all activities will have a value.
Tip
Click a column header under Results to sort the results. You can sort the results from A to Z or Z to A. Click the Date header to sort the results from oldest to newest or newest to oldest.
View the details for a specific event
You can view more details about an event by clicking the event record in the list of search results. A Details page is displayed that contains the detailed properties from the event record. The properties that are displayed depend on the Office 365 service in which the event occurs. To display these details, click More information. For descriptions, see Detailed properties in the Office 365 audit log.
Step 3: Filter the search results
In addition to sorting, you can also filter the results of an audit log search. This is a great feature that can help you quickly filter the results for a specific user or activity. You can initially create a wide search and then quickly filter the results to see specific events. Then you can narrow the search criteria and re-run the search to return a smaller, more concise set of results.
To filter the results:
Run an audit log search.
When the results are displayed, click Filter results.
Keyword boxes are displayed under each column header.
Click one of the boxes under a column header and type a word or phrase, depending on the column you're filtering on. The results will dynamically readjust to display the events that match your filter.
To clear a filter, click the X in the filter box or just click Hide filtering.
Tip
To display events from the Exchange admin audit log, type a - (dash) in the Activity filter box. This will display cmdlet names, which are displayed in the Activity column for Exchange admin events. Then you can sort the cmdlet names in alphabetical order.
Step 4: Export the search results to a file
You can export the results of an audit log search to a comma separated value (CSV) file on your local computer. You can open this file in Microsoft Excel and use features such as search, sorting, filtering, and splitting a single column (that contains multi-value cells) into multiple columns.
Run an audit log search, and then revise the search criteria until you have the desired results.
Click Export results and select one of the following options:
Save loaded results Choose this option to export only the entries that are displayed under Results on the ** Audit log search ** page. The CSV file that is downloaded contains the same columns (and data) displayed on the page (Date, User, Activity, Item, and Details). An additional column (named More) is included in the CSV file that contains more information from the audit log entry. Because you're exporting the same results that are loaded (and viewable) on the Audit log search page, a maximum of 5,000 entries are exported.
Download all results Choose this option to export all entries from the Office 365 audit log that meet the search criteria. For a large set of search results, choose this option to download all entries from the audit log in addition to the 5,000 results that can be displayed on the Audit log search page. This option will download the raw data from the audit log to a CSV file, and contains additional information from the audit log entry in a column named AuditData. It may take longer to download the file if you choose this export option because the file may be much larger than the one that's downloaded if you choose the other option.
Important
You can download a maximum of 50,000 entries to a CSV file from a single audit log search. If 50,000 entries are downloaded to the CSV file, you can probably assume there are more than 50,000 events that met the search criteria. To export more than this limit, try using a date range to reduce the number of audit log entries. You might have to run multiple searches with smaller date ranges to export more than 50,000 entries.
- After you select an export option, a message is displayed at the bottom of the window that prompts you to open the CSV file, save it to the Downloads folder, or save it to a specific folder.
More information about exporting audit log search results
The Download all results option downloads the raw data from the Office 365 audit log to a CSV file. This file contains different column names (CreationDate, UserIds, Operation, AuditData) than the file that's downloaded if you select the Save loaded results option. The values in the two different CSV files for the same activity may also be different. For example, the activity in the Action column in the CSV file and may have a different value than the "user-friendly" version that's displayed in the Activity column on the Audit log search page; for example, MailboxLogin vs. User signed in to mailbox.
If you download all results, the CSV file contains a column named AuditData, which contains additional information about each event. As previously stated, this column contains a multi-value property for multiple properties from the audit log record. Each of the property:value pairs in this multi-value property are separated by a comma. You can use the Power Query in Excel to split this column into multiple columns so that each property will have its own column. This will let you sort and filter on one or more of these properties. To learn how to do this, see the "Split a column by delimiter" section in Split a column of text (Power Query).
After you split the AuditData column, you can filter on the Operations column to display the detailed properties for a specific type of activity.
There's a 3,060-character limit for the data that's displayed in the AuditData field for an audit record. If the 3,060-character limit is exceeded, the data in this field is truncated.
When you download all results from a search query that contains events from different Office 365 services, the AuditData column in the CSV file contains different properties depending on which service the action was performed in. For example, entries from Exchange and Azure AD audit logs include a property named ResultStatus that indicates if the action was successful or not. This property isn't included for events in SharePoint. Similarly, SharePoint events have a property that identifies the site URL for file and folder related activities. To mitigate this behavior, consider using different searches to export the results for activities from a single service.
For a description of the properties that are listed in the AuditData column in the CSV file when you download all results, and the service each one applies to, see Detailed properties in the Office 365 audit log.
Audited activities
The tables in this section describe the activities that are audited in Office 365. You can search for these events by searching the audit log in the security and compliance center.
These tables group related activities or the activities from a specific Office 365 service. The tables include the friendly name that's displayed in the Activities drop-down list and the name of the corresponding operation that appears in the detailed information of an audit record and in the CSV file when you export the search results. For descriptions of the detailed information, see Detailed properties in the Office 365 audit log.
Click one of the following links to go to a specific table.
File and page activities
The following table describes the file and page activities in SharePoint Online and OneDrive for Business.

User or system account accesses a file. |
| (none) |
FileAccessedExtended |
This is related to the "Accessed file" (FileAccessed) activity. A FileAccessedExtended event is logged when the same person continually accesses a file for an extended period of time (up to 3 hours). The purpose of logging FileAccessedExtended events is to reduce the number of FileAccessed events that are logged when a file is continually accessed. This helps reduce the noise of multiple FileAccessed records for what is essentially the same user activity, and lets you focus on the initial (and more important) FileAccessed event. |

| Modified file |
FileModified |
User or system account modifies the content or the properties of a document located on a site. |
| (none) |
FileModifiedExtended |
This is related to the "Modified file" (FileModified) activity. A FileModifiedExtended event is logged when the same person continually modifies a file for an extended period of time (up to 3 hours). The purpose of logging FileModifiedExtended events is to reduce the number of FileModified events that are logged when a file is continually modified. This helps reduce the noise of multiple FileModified records for what is essentially the same user activity, and lets you focus on the initial (and more important) FileModified event. |
| Moved file |
FileMoved |
User moves a document from its current location on a site to a new location. |
| Recycled all minor versions of file |

Sharing and access request activities
The following table describes the user sharing and access request activities in SharePoint Online and OneDrive for Business. For sharing events, the Detail column under Results identifies the name of the user or group the item was shared with and whether that user or group is a member or guest in your organization. For more information, see Use sharing auditing in the Office 365 audit log.
Note
Users can be either members or guests based on the UserType property of the user object. A member is usually an employee, and a guest is usually a collaborator outside of your organization. When a user accepts a sharing invitation (and isn't already part of your organization), a guest account is created for them in your organization's directory. Once the guest user has an account in your directory, resources may be shared directly with them (without requiring an invitation).

Synchronization activities
The following table lists file synchronization activities in SharePoint Online and OneDrive for Business.
| Friendly name | Operation | Description |
|---|---|---|
| Allowed computer to sync files |
ManagedSyncClientAllowed |
User successfully establishes a sync relationship with a site. The sync relationship is successful because the user's computer is a member of a domain that's been added to the list of domains (called the safe recipients list ) that can access document libraries in your organization. For more information about this feature, see Use Windows PowerShell cmdlets to enable OneDrive sync for domains that are on the safe recipients list. |
| Blocked computer from syncing files |
UnmanagedSyncClientBlocked |
User tries to establish a sync relationship with a site from a computer that isn't a member of your organization's domain or is a member of a domain that hasn't been added to the list of domains (called the safe recipients list) that can access document libraries in your organization. The sync relationship is not allowed, and the user's computer is blocked from syncing, downloading, or uploading files on a document library. For information about this feature, see Use Windows PowerShell cmdlets to enable OneDrive sync for domains that are on the safe recipients list. |
| Downloaded files to computer |
FileSyncDownloadedFull |

The most used Office 365 services like Exchange Online, SharePoint Online, OneDrive for Business, Azure Active Directory, Microsoft Teams, Dynamics 365, Advanced Threat Protection, and Power BI are audited. See the beginning of this article for a list of services that are audited.
What activities are audited by auditing service in Office 365?
See the Audited activities section in this article for a list and description of the activities that are audited in Office 365.
How long does it take for an auditing record to be available after an event has occurred?
Most auditing data is available within 30 minutes but it may take up to 24 hours after an event occurs for the corresponding audit log entry to be displayed in the search results. See the table in the Before you begin section of this article that shows the time it takes for events in the different Office 365 services to be available.
How long are the audit records retained for?
As previously explained, the retention period for audit records depends on your organization's Office 365 subscription.
Office 365 E3 - Audit records are retained for 90 days.
Office 365 E5 - Audit records are also retained for 90 days. Retaining audit records for one year may eventually be available for E5 users and users with an E3 license and an Office 365 Advanced Compliance add-on license.
Note
As previously explained, the private preview program for the one-year retention period for audit records for E5 organizations (or E3 organizations that have Advanced Compliance add-on licenses) is closed to new enrollment. This article will be updated when the one-year retention period is available in public preview or released for general availability.
Also note that the duration of the retention period for audit records is based on per-user licensing. For example, if a user in your organization is assigned an Office 365 E3 or E5 license, then the audit records for activities performed by that user are retained for 90 days.
Can I access the auditing data programmatically?
Yes. The Office 365 Management Activity API is used to fetch the audit logs programmatically. To get started, see Get started with Office 365 Management APIs.
Are there other ways to get auditing logs other than using the security and compliance center or the Office 365 Management Activity API?
No. These are the only two ways to get data from the Office 365 auditing service.
Do I need to individually enable auditing in each service that I want to capture audit logs for?
In most Office 365 services, auditing is enabled by default after you initially turn on auditing for your Office 365 organization (as described in the Before you begin section in this article). However, you have to enable mailbox auditing in Exchange Online for each mailbox that you want to audit. We are working on enabling mailbox auditing by default for all mailboxes in an Office 365 organization. For more information, see "Exchange mailbox auditing will be enabled by default" in the Microsoft Security, Privacy, and Compliance blog.
Does the Office 365 auditing service support de-duplication of records?
No. The auditing service pipeline is near real time, and therefore can't support de-duplication.
Does Office 365 auditing data flow across geographies?
No. We currently have auditing pipeline deployments in the NA (North America), EMEA (Europe, Middle east and Africa) and APAC (Asia Pacific) regions. However, we may flow the data across these regions for load-balancing and only during live-site issues. When we do perform these activities, the data in transit is encrypted.
Is auditing data encrypted?
Auditing data is stored in Exchange mailboxes (data at rest) in the same region where the auditing pipeline is deployed. This data is not encrypted. However, data in transit is always encrypted.
