The question nobody dares to ask! How do you create a new user in a hybrid environment.
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.
We just started doing it this way: (Hybrid Exchange and Skype)
1. We run set-aduser, and set the minimal Exchange and Lync attributes that portray that a user has already been migrated. (You can look at an already migrated user to see what is set at migration)
2. Sync.
3. Assign license.
The mailbox and Skype/teams accounts are created online and believe they were migrated. The on-prem servers are fully aware of the accounts and believes they were migrated.
