Properties

diagnostics	Provides diagnostic information to an Outlook add-in. Contains the following members. `hostName` (string): A string that represents the name of the Office application. It should be one of the following values: `Outlook`, `OutlookWebApp`, `OutlookIOS`, or `OutlookAndroid`. Note: The "Outlook" value is returned for Outlook on desktop clients (i.e., Windows and Mac). `hostVersion` (string): A string that represents the version of either the Office application or the Exchange Server (e.g., "15.0.468.0"). If the mail add-in is running in Outlook on desktop or on mobile clients, the `hostVersion` property returns the version of the application, Outlook. In Outlook on the web, the property returns the version of the Exchange Server. `OWAView` (`MailboxEnums.OWAView` or string): An enum (or string literal) that represents the current view of Outlook on the web. If the application is not Outlook on the web, then accessing this property results in undefined. Outlook on the web has three views (`OneColumn` - displayed when the screen is narrow, `TwoColumns` - displayed when the screen is wider, and `ThreeColumns` - displayed when the screen is wide) that correspond to the width of the screen and the window, and the number of columns that can be displayed. More information is under Office.Diagnostics.
ewsUrl	Gets the URL of the Exchange Web Services (EWS) endpoint for this email account.
item	The mailbox item. Depending on the context in which the add-in opened, the item type may vary. If you want to see IntelliSense for only a specific type or mode, cast this item to one of the following: MessageCompose, MessageRead, AppointmentCompose, AppointmentRead Important: `item` can be null if your add-in supports pinning the task pane. For details on how to handle, see Implement a pinnable task pane in Outlook.
userProfile	Information about the user associated with the mailbox. This includes their account type, display name, email address, and time zone. More information is under Office.UserProfile

Methods

convertToLocalClientTime(timeValue)	Gets a dictionary containing time information in local client time. The dates and times used by a mail app for Outlook on the web or on desktop clients can use different time zones. Outlook uses the client computer time zone; Outlook on the web uses the time zone set on the Exchange Admin Center (EAC). You should handle date and time values so that the values you display on the user interface are always consistent with the time zone that the user expects. If the mail app is running in Outlook on desktop clients, the `convertToLocalClientTime` method will return a dictionary object with the values set to the client computer time zone. If the mail app is running in Outlook on the web, the `convertToLocalClientTime` method will return a dictionary object with the values set to the time zone specified in the EAC.
convertToUtcClientTime(input)	Gets a `Date` object from a dictionary containing time information. The `convertToUtcClientTime` method converts a dictionary containing a local date and time to a `Date` object with the correct values for the local date and time.
displayAppointmentForm(itemId)	Displays an existing calendar appointment. The `displayAppointmentForm` method opens an existing calendar appointment in a new window on the desktop. In Outlook on Mac, you can use this method to display a single appointment that isn't part of a recurring series, or the master appointment of a recurring series. However, you can't display an instance of the series because you can't access the properties (including the item ID) of instances of a recurring series. In Outlook on the web, this method opens the specified form only if the body of the form is less than or equal to 32K characters. If the specified item identifier does not identify an existing appointment, a blank pane opens on the client computer or device, and no error message is returned.
displayMessageForm(itemId)	Displays an existing message. The `displayMessageForm` method opens an existing message in a new window on the desktop. In Outlook on the web, this method opens the specified form only if the body of the form is less than or equal to 32K characters. If the specified item identifier doesn't identify an existing message, no message will be displayed on the client computer, and no error message is returned.
displayNewAppointmentForm(parameters)	Displays a form for creating a new calendar appointment. The `displayNewAppointmentForm` method opens a form that enables the user to create a new appointment or meeting. If parameters are specified, the appointment form fields are automatically populated with the contents of the parameters. In Outlook on the web, this method always displays a form with an attendees field. If you don't specify any attendees as input arguments, the method displays a form with a Save button. If you have specified attendees, the form would include the attendees and a Send button. In the Outlook rich client and Outlook RT, if you specify any attendees or resources in the `requiredAttendees`, `optionalAttendees`, or `resources` parameter, this method displays a meeting form with a Send button. If you don't specify any recipients, this method displays an appointment form with a Save & Close button. If any of the parameters exceed the specified size limits, or if an unknown parameter name is specified, an exception is thrown.
getCallbackTokenAsync(callback, userContext)	Gets a string that contains a token used to get an attachment or item from an Exchange Server. The `getCallbackTokenAsync` method makes an asynchronous call to get an opaque token from the Exchange Server that hosts the user's mailbox. The lifetime of the callback token is 5 minutes. The token is returned as a string in the `asyncResult.value` property.
getUserIdentityTokenAsync(callback, userContext)	Gets a token identifying the user and the Office Add-in. The token is returned as a string in the `asyncResult.value` property.
makeEwsRequestAsync(data, callback, userContext)	Makes an asynchronous request to an Exchange Web Services (EWS) service on the Exchange server that hosts the user's mailbox. The `makeEwsRequestAsync` method sends an EWS request on behalf of the add-in to Exchange.

getCallbackTokenAsync(callback, userContext)

Gets a string that contains a token used to get an attachment or item from an Exchange Server.

The getCallbackTokenAsync method makes an asynchronous call to get an opaque token from the Exchange Server that hosts the user's mailbox. The lifetime of the callback token is 5 minutes.

The token is returned as a string in the asyncResult.value property.

getCallbackTokenAsync(callback: (asyncResult: Office.AsyncResult<string>) => void, userContext?: any): void;

Parameters

callback: (asyncResult: Office.AsyncResult<string>) => void

When the method completes, the function passed in the callback parameter is called with a single parameter of type Office.AsyncResult. The token is returned as a string in the asyncResult.value property. If there was an error, the asyncResult.error and asyncResult.diagnostics properties may provide additional information.

userContext: any

Optional. Any state data that is passed to the asynchronous method.

Returns

void

Remarks

[ API set: All support Read mode; Mailbox 1.3 introduced Compose mode support ]

Minimum permission level: read item

Applicable Outlook mode: Compose or Read

Important:

In October 2024, legacy Exchange user identity and callback tokens will be turned off by default for all Exchange Online tenants. This is part of Microsoft's Secure Future Initiative, which gives organizations the tools needed to respond to the current threat landscape. Exchange user identity tokens will still work for Exchange on-premises. Nested app authentication is the recommended approach for tokens going forward. For more information, see our blog post and FAQ page.
You can pass both the token and either an attachment identifier or item identifier to an external system. That system uses the token as a bearer authorization token to call the Exchange Web Services (EWS) GetAttachment or GetItem operation to return an attachment or item. For example, you can create a remote service to get attachments from the selected item.
Calling the getCallbackTokenAsync method in read mode requires a minimum permission level of read item.
Calling the getCallbackTokenAsync method in compose mode requires you to have saved the item. The saveAsync method requires a minimum permission level of read/write item.
This method isn't supported in Outlook on Android or on iOS. EWS operations aren't supported in add-ins running in Outlook on mobile clients. For more information on supported APIs in Outlook mobile, see Outlook JavaScript APIs supported in Outlook on mobile devices.
For guidance on delegate or shared scenarios, see the shared folders and shared mailbox article.

Errors:

HTTPRequestFailure: The request has failed. Please look at the diagnostics object for the HTTP error code.
InternalServerError: The Exchange server returned an error. Please look at the diagnostics object for more information.
NetworkError: The user is no longer connected to the network. Please check your network connection and try again.

        console.error(`Token retrieval failed with message: ${result.error.message}`);
    } else {
        console.log(result.value);
    }
});

makeEwsRequestAsync(data, callback, userContext)

Makes an asynchronous request to an Exchange Web Services (EWS) service on the Exchange server that hosts the user's mailbox.

The makeEwsRequestAsync method sends an EWS request on behalf of the add-in to Exchange.

makeEwsRequestAsync(data: any, callback: (asyncResult: Office.AsyncResult<string>) => void, userContext?: any): void;

Parameters

data: any

The EWS request.

callback: (asyncResult: Office.AsyncResult<string>) => void

When the method completes, the function passed in the callback parameter is called with a single parameter, asyncResult, which is an Office.AsyncResult object. The XML response of the EWS request is provided as a string in the asyncResult.value property. In Outlook on the web, on Windows (starting in Version 2303 (Build 16225.10000)), and on Mac (starting in Version 16.73 (23042601)), if the response exceeds 5 MB in size, an error message is returned in the asyncResult.error property. In earlier versions of the Outlook desktop client, an error message is returned if the response exceeds 1 MB in size.

userContext: any

Optional. Any state data that is passed to the asynchronous method.

Returns

void

Important:

In October 2024, legacy Exchange user identity and callback tokens will be turned off by default for all Exchange Online tenants. This is part of Microsoft's Secure Future Initiative, which gives organizations the tools needed to respond to the current threat landscape. Exchange user identity tokens will still work for Exchange on-premises. Nested app authentication is the recommended approach for tokens going forward. For more information, see our blog post and FAQ page.
To enable the makeEwsRequestAsync method to make EWS requests, the server administrator must set OAuthAuthentication to true on the Client Access Server EWS directory .
Your add-in must have the read/write mailbox permission to use the makeEwsRequestAsync method. For information about using the read/write mailbox permission and the EWS operations that you can call with the makeEwsRequestAsync method, see Specify permissions for mail add-in access to the user's mailbox.
If your add-in needs to access Folder Associated Items or its XML request must specify UTF-8 encoding (\<?xml version="1.0" encoding="utf-8"?\>), it must use Microsoft Graph or REST APIs to access the user's mailbox instead.
This method isn't supported in Outlook on Android or on iOS. For more information on supported APIs in Outlook mobile, see Outlook JavaScript APIs supported in Outlook on mobile devices.
This method isn't supported when the add-in is loaded in a Gmail mailbox.
When you use the makeEwsRequestAsync method in add-ins that run in Outlook versions earlier than Version 15.0.4535.1004, you must set the encoding value to ISO-8859-1 (<?xml version="1.0" encoding="iso-8859-1"?>). To determine the version of an Outlook client, use the mailbox.diagnostics.hostVersion property. You don't need to set the encoding value when your add-in is running in Outlook on the web. To determine the Outlook client in which your add-in is running, use the mailbox.diagnostics.hostName property.

Examples

function getSubjectRequest(id) {
    // Return a GetItem operation request for the subject of the specified item.
