Can I add new domains to the WOPI domain allow list after launch?

Yes, domains can be added or existing domains changed after launch. However, we do request that these changes be relatively infrequent, and encourage hosts to use a domain scheme that does not require constant changes.

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


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
