We are planning to start cloud mailbox provision. At present we are stuck with shared mailbox permission issue. basically you can take advantage of any of this PS command New-RemoteMailbox, Enable-RemoteMailbox, Set-RemoteMailbox to create Shared mailbox in EXO. problem is after that how can we grant SendAs and Full Access permission as there is no remote command available for Add-MailboxPermission.
Issue is if you are creating shared mailbox using script you will have to silent your script for 30 minutes or go in loop until this is replicated on Azure-AD. You can not run Add-MailboxPermission until mailbox is provision on EXO.
Has anyone came up with solution to grant mailbox permission with minimum admin activity?
