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.

Important

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.
