Hi,
we have the following setup:
2 Mailbox Servers, 1 DAG, 2 Mailbox Stores
MD1
MD2
We need to create a new mailbox store MD3 and move all mailboxes to that store.
i think, we can move all mailboxes with one run using Exchange Powershell, right?
When we move the mailboxes, will they be unavailable while moving or is there just a short interruption, when while finishing the move?
