We plan to discuss removing our O365 hybrid next week as we're implementing Okta - which apparently does not like a hybrid mail server. Although we chose keeping the hybrid server onprem when going to O365, all our mailboxes reside in the cloud - we kept they hybrid server onprem as we were told by our implementer we could roll back from O365 if we had issues. Now, mgmt wants to remove it completely.
We did talk to MS previously, and they stated user configurations required keeping the hybrid server if that config was chosen originally (obviously was). Adsiedit would need to be used to update exch attributes on user objects, and that's not supported. If you have probs, it's best effort ONLY.
** I need specific points to discuss with mgmt:
- What would be the specific issues we COULD run into that i can warn mgmt about so they can make the most educated choice if they go the unsupported chance, or not? We no longer have MS premier support, so i can no longer call them directly.
- what can i advise them could be the specific issues if we did this?
