Method Details
appendOnSendAsync(data, options, callback)
Appends on send the specified content to the end of the item body, after any signature.
To use appendOnSendAsync
, you must specify a supplementary permission in the manifest. Details vary with the type of manifest. See Understanding Outlook add-in permissions. To learn more about append-on-send and its configuration, see Implement append-on-send in your Outlook add-in.
appendOnSendAsync(data: string, options: Office.AsyncContextOptions & CoercionTypeOptions, callback?: (asyncResult: Office.AsyncResult<void>) => void): void;
Parameters
- data
-
string
The string to be added to the end of the body. The string is limited to 5,000 characters.
An object literal that contains one or more of the following properties:- asyncContext
: Developers can provide any object they wish to access in the callback function. coercionType
: The desired format for the data to be appended. The string in the data
parameter will be converted to this format.
- callback
-
(asyncResult: Office.AsyncResult<void>) => void
Optional. When the method completes, the function passed in the callback
parameter is called with a single parameter of type Office.AsyncResult
. Any errors encountered will be provided in the asyncResult.error
property.
Returns
void
Remarks
Minimum permission level: read/write item
Applicable Outlook mode: Compose
Recommended: Call getTypeAsync
, then pass its returned value to the options.coercionType
parameter.
Important:
If the user is running add-ins that implement the on-send feature using
ItemSend
in the manifest, append-on-send runs before on-send functionality.If your add-in implements the on-send feature and calls
appendOnSendAsync
in theItemSend
handler, theappendOnSendAsync
call returns an error as this scenario isn't supported.To clear data from a previous
appendOnSendAsync
call, you can call it again with thedata
parameter set tonull
.SVG files aren't supported. Use JPG or PNG files instead.
The
appendOnSendAsync
method doesn't support inline CSS. Use internal or external CSS instead.
Errors:

Parameters
- data
-
string
The string to be inserted at the beginning of the body. The string is limited to 1,000,000 characters.
An object literal that contains one or more of the following properties:- asyncContext
: Developers can provide any object they wish to access in the callback function. coercionType

Important:
After the content is prepended, the position of the cursor depends on which client the add-in is running. In Outlook on the web and on Windows (new and classic), the cursor position remains the same in the preexisting content of the body. For example, if the cursor was positioned at the beginning of the body prior to the
prependAsync
call, it will appear between the prepended content and the preexisting content of the body after the call. In Outlook on Mac, the cursor position isn't preserved. The cursor disappears after theprependAsync
call and only reappears when the user selects something in the body of the mail item.When working with HTML-formatted bodies, it's important to note that the client may modify the value passed to
prependAsync
to make it render efficiently with its rendering engine. This means that the value returned from a subsequent call to theBody.getAsync
method (introduced in Mailbox 1.3) won't necessarily contain the exact value that was passed in the previousprependAsync
call.When including links in HTML markup, you can disable online link preview by setting the

The content of the last run add-in appears above previously prepended content.If the add-in attempts to insert HTML into a plain text body, the content won't be prepended. Conversely, plain text will be inserted into an HTML body.
SVG files aren't supported. Use JPG or PNG files instead.
The
prependOnSendAsync
method doesn't support inline CSS. Use internal or external CSS instead.
Errors:
DataExceedsMaximumSize

setAsync(data, options, callback)
Replaces the entire body with the specified text.
setAsync(data: string, options: Office.AsyncContextOptions & CoercionTypeOptions, callback?: (asyncResult: Office.AsyncResult<void>) => void): void;
Parameters
- data
-
string
The string that will replace the existing body. The string is limited to 1,000,000 characters.
An object literal that contains one or more of the following properties:- asyncContext
: Developers can provide any object they wish to access in the callback function. coercionType
: The desired format for the body. The string in the data
parameter will be converted to this format.
- callback
-
(asyncResult: Office.AsyncResult<void>) => void
Optional. When the method completes, the function passed in the callback
parameter is called with a single parameter of type Office.AsyncResult. Any errors encountered will be provided in the asyncResult.error
property.
Returns
void
Remarks
Minimum permission level: read/write item
Applicable Outlook mode: Compose
Recommended: Call getTypeAsync
, then pass the returned value to the options.coercionType
parameter.
Important:
After the body is replaced with the specified content, the position of the cursor depends on which client the add-in is running. In classic Outlook on Windows, the cursor appears at the beginning of the body of the mail item. In Outlook on the web and new Outlook on Windows, the cursor appears at the end of the body of the mail item. In Outlook on Mac, the cursor position isn't preserved. The cursor disappears after the
prependAsync
call and only reappears when the user selects something in the body of the mail item.When working with HTML-formatted bodies, it's important to note that the value returned by the
Body.getAsync
method won't necessarily be the exact same value that was previously passed in theBody.setAsync
method. The client may modify the value passed tosetAsync
to make it render efficiently with its rendering engine.When including links in HTML markup, you can disable online link preview by setting the
id
attribute on the anchor (<a>) to "LPNoLP" (see the Examples section for a sample).In Outlook on Windows and on Mac, the add-in user isn't able to revert this action with the Undo command.
In Outlook on Android and on iOS, this method isn't supported in the Message Compose mode. Only the Appointment Organizer mode is supported. For more information on supported APIs in Outlook mobile, see Outlook JavaScript APIs supported in Outlook on mobile devices.
SVG files aren't supported. Use JPG or PNG files instead.
The
setAsync
method doesn't support inline CSS. Use internal or external CSS instead.
