I have all mailboxes up in 365 as part of a Hybrid with ADSync, each new user is created on premise, mailbox first to insure the attributes are there before the sync and then the mailbox is moved up to 365.
If I create the AD account with no mailbox then it creates in 365 with no email policy and some mailboxes I would need to edit from onprem and some in 365. To be able to keep the being able to edit exchange attributes through the onprem existing exchange server, how should I handle this? Regards, Paul.
