The question nobody dares to ask! How do you create a new user in a hybrid environment.
Hi, the last couple fo days the question how to create a new user in a hybrid exchange environment is floating around in my head. Most of the time when i create a user i create a onpremise accoun...
The best practice is whatever works for your user management workflows. You can create it either way. In a hybrid you can move mailboxes back and forth whether they were created on-prem or in the cloud.
One caveat with New-RemoteMailbox is that it can't do Shared mailboxes. Those you need to create on-prem and then move, or, create in EXO as a user mailbox and then convert to Shared. Either way, same result.
If you own Azure AD Premium (or EMS or SPE license) then you can simplify this process down to one step
Step 1: Create the Remote mailbox.
How is this possible?
Creating a remote mailbox automatically creates the AD account. Then, AAD Sync will sync every 30 minutes (by default) and that will create the account after the new remote mailbox command is issued from on-prem. So no real need to force a sync unless you are in a hurry.
Azure AD Premium will automatically License the user. Instructions on setting that up are here:
This is all now possible due to the new Azure AD Premium feature, which lets you assign licenses based on group membership, or even dynamic membership.
Yeah, only thing that is missing for replacing my script is the advanced auditing settings for the Exchange mailbox, but maybe there is something I am not aware of.

For me, the only way to make it that let you migrate the mailbox from EXO to On Prem and vice- versa without issue, still to create the AD account on prem, create the mailbox on prem and migrate it to EXO.
Since the AAD Sync still one way.
