Hi Team
We have migrated mailboxes from a domain called Domain A(Source) into Domain B(Destination).
Please note:Domain A and Domain B both are in M365 Tenant.
I am looking to remove domain A from Source -M365(then Shut down) and add Domain A to my MS 365 Tennant(Destination)
Movement of Domain to Destination MS365 tenant is to retain the domain name and be able to use the smtp(Alias) mask on the mailboxes migrated into Domain B.
Do we have any emails outage time in this process?
