VersionOverrides element

  • Article

This element contains information for features that aren't supported in the base manifest. Its child markup may override some of the markup in the base manifest (or in a parent <VersionOverrides>). <VersionOverrides> is a child element of either the root OfficeApp element in the manifest or a parent <VersionOverrides> element. This element is supported in manifest schema v1.1 and later but is defined in separate VersionOverrides schemas.

For more information, see Version overrides in the add-in only manifest.

Attributes

Attribute Required Description
xmlns Yes The VersionOverrides schema namespace. The allowed values vary depending on this <VersionOverrides> element's xsi:type value and the xsi:type value of the parent <OfficeApp> element. See Namespace values below.
xsi:type Yes The schema version. At this time, the only valid values are VersionOverridesV1_0 and VersionOverridesV1_1.

Namespace values

The following lists the required value of the xmlns attribute depending on the xsi:type value of the root <OfficeApp> element.

  • TaskPaneApp supports only version 1.0 of VersionOverrides, and the xmlns must be http://schemas.microsoft.com/office/taskpaneappversionoverrides.
  • ContentApp supports only version 1.0 of VersionOverrides, and the xmlns must be http://schemas.microsoft.com/office/contentappversionoverrides.
  • MailApp supports versions 1.0 and 1.1 of VersionOverrides, so the value of xmlns varies depending on this <VersionOverrides> element's xsi:type value:
    • When xsi:type is VersionOverridesV1_0, xmlns must be http://schemas.microsoft.com/office/mailappversionoverrides.
    • When xsi:type is VersionOverridesV1_1, xmlns must be http://schemas.microsoft.com/office/mailappversionoverrides/1.1.

Note

Currently only Outlook 2016 or later supports the VersionOverrides v1.1 schema and the VersionOverridesV1_1 type.

Variant schemas

There is a different schema for each of the possible xmlns values, so each has a separate reference page.
