Can I add more than one domain to the WOPI domain allow list?

Yes, you can have multiple entries on both the test and production allow lists.

Contact Microsoft Support to request changes to your domain entries.

Important

Changes to settings require time to make. Any changes to Microsoft-configured settings will take 2-3 weeks to fully roll out. This includes changes to the WOPI domain allow list, and applies to both the production and test environments
