Write back of users from AAD to AD with Exchange Hybrid?

Copper Contributor

Is it possible to provision new users over Graph API and write them back to on-prem AD with Exchange Hybrid? All mailboxes are in Exchange Online.

Hi @Magnus Tengmo,


You have to create your mailboxes using your On-Premises Exchange to synchronize to Office 365.


You can create using the powershell new-remotemailbox https://docs.microsoft.com/en-us/powershell/module/exchange/federation-and-hybrid/new-remotemailbox?... 


The attributes synchronized are described here https://docs.microsoft.com/en-us/azure/active-directory/connect/active-directory-aadconnectsync-attr...
