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 via the CSPP Yammer group to request changes to your domain entries.


Changes to production settings require time to make.

Any changes to Microsoft-configured settings will take 2-3 weeks to fully roll out to the production environment. This includes changes to the WOPI domain allow list.

The test environment, on the other hand, is generally updated with new settings within 24-48 hours.
