EquivalentAddin element

Specifies backwards compatibility for an equivalent COM add-in, VSTO add-in, or XLL.

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.

  • Excel, Word, and PowerPoint on Windows (Version 1904 or later)
  • Outlook on Windows (Version 2102 or later) against a supported Exchange server version
    • Exchange Online
    • Exchange 2019 Cumulative Update 10 or later (KB5003612)
    • Exchange 2016 Cumulative Update 21 or later (KB5003611)

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.

Remarks

To specify a COM or VSTO add-in as the equivalent add-in, provide both the ProgId and Type elements.

Note

  • Although the term "ProgId" is usually associated with only COM add-ins, in the manifest it refers to the name of either a COM or VSTO add-in.
  • Use COM as the value of the Type element for both COM and VSTO add-ins.

To specify an XLL as the equivalent add-in, provide both the FileName and Type elements.
