Important
The equivalent add-in feature is supported by the following platform and applications. COM and VSTO add-ins can't be installed on any other platform, so on those platforms the manifest element that's discussed later in this article is ignored.
Add-in type: Task pane, Mail, Custom function
Valid only in these VersionOverrides schemas:
- Task pane 1.0
- Mail 1.1
For more information, see Version overrides in the add-in only manifest.
