we used to be able to change smtp addresses via the o365 console. Appears this update has been rolled out to multiple customers of mine now and We have lost this functionality. Changes have to now be done on-prem and synced to 365. 

 

Getting this error in EXO/O365:

DualWrite (Graph) RequestId: The issue may be transient and please retry a couple of minutes later. If issue persists, please see exception members for more information.

 

Is there a way to turn off the dual-write feature?
