Dialog Origin requirement sets

Requirement sets are named groups of API members. Office Add-ins use requirement sets specified in the manifest or use a runtime check to determine whether an Office application supports APIs that an add-in needs. For more information, see Office versions and requirement sets.

Office Add-ins run across multiple versions of Office. The following table lists the Dialog Origin requirement sets, the supported Office client applications, and the minimum builds or versions for those applications where applicable.
