Control access to SharePoint Online and OneDrive data based on network location

As an IT admin, you can control access to SharePoint and OneDrive resources based on defined network locations that you trust. This is also known as location-based policy.

To do this, you define a trusted network boundary by specifying one or more authorized IP address ranges. Any user who attempts to access SharePoint and OneDrive from outside this network boundary (using web browser, desktop app, or mobile app on any device) will be blocked.

Here are some important considerations for setting a location-based policy:

  • External Sharing: As per the policy, users who try to access SharePoint resources from outside the defined IP address range will be blocked, including guest users outside of the range with whom files have been externally shared.

  • Access from first and third-party apps: Normally, a SharePoint document can be accessed from apps like Exchange, Yammer, Skype, Teams, Planner, Flow, PowerBI, PowerApps, OneNote, and so on. When a location-based policy is enabled, apps that do not support location-based policies are blocked. The only apps that currently support location-based policies are Teams, Yammer, and Exchange. This means that all other apps are blocked, even when these apps are hosted within the trusted network boundary. This is because SharePoint cannot determine whether a user of these apps is within the trusted boundary.

    Note

    We recommend that when a location-based policy is enabled for SharePoint, the same policy and IP address ranges should be configured for Exchange and Yammer. SharePoint relies on these services to enforce that the users of these apps are within the trusted IP range.

  • Access from dynamic IP ranges: Several services and providers host apps which have dynamic originating IP addresses. For example, a service that accesses SharePoint while running from one Azure data center may start running from a different data center due to a failover condition or other reason, thus dynamically changing its IP address. The location-based conditional access policy relies on fixed, trusted IP address ranges. If the IP address range cannot be determined up front, location-based policy may not be an option for your environment.

Note

It can take up to 15 minutes for these settings to take effect.

  1. Sign in to https://admin.microsoft.com as a global or SharePoint admin. (If you see a message that you don't have permission to access the page, you don't have Office 365 administrator permissions in your organization.)

    Note

    If you have Office 365 Germany, sign in at https://portal.office.de. If you have Office 365 operated by 21Vianet (China), sign in at https://login.partner.microsoftonline.cn/. Then select the Admin tile to open the admin center.

  2. In the left pane, under Admin centers, select SharePoint. (You might need to select Show all to see the list of admin centers.)

  3. If the classic SharePoint admin center appears, select Open it now at the top of the page to open the new SharePoint admin center. .

  4. In the left pane of the new SharePoint admin center, select Access control.

  5. Select Network location and turn on Allow access only from specific IP address ranges.

  6. Enter IP addresses and address ranges separated by commas.

    Important

    Make sure you include your own IP address so you don't lock yourself out. This setting not only restricts access to OneDrive and SharePoint sites, but also to the OneDrive and SharePoint admin centers, and to running PowerShell cmdlets. If you lock yourself out and can't connect from an IP address within a range you specified, you will need to contact Support for help.

Note

To set a location-based policy by using PowerShell, run Set-SPOTenant with the -IPAddressAllowList parameter. For more info, see Set-SPOTenant.”
