Hi,
I am running Exchange Hybrid setup, Exchange 2019 with Exchange online. All our mailboxes (user\shared\room etc.) are migrated to Exchange online. All the users & room mailboxes has 'IsDirSynced' property value of 'TRUE'. AzureAD connect is in place for AD sync.
Now I want to cerate new Room Mailbox. Shall I create it in Exchange Online EAC directly or on On-prem Exchange ECP?
Anybody has some tips about what would be the best practice going forward to create Room\Shared mailbox?
