I have an issue where users cannot email mailboxes that used to be on the same exchange 2013 server now that they have been moved to a different exchange 2013 server
So domain A and Domain B were on the same server and could email each other without an issue, Domain B has now moved to a different server and is working correctly however when users of Domain A try to email users of Domain B they get a bounce back stating that the database for domain B is offline '432 4.3.2 STOREDRV; mailbox database is offline;
I have asked users of domain A to delete their autocomplete files and rewrite the addresses of users at domain B but they seem to still be getting the same message
I have removed domain B as an accepted domain in the ECP on the Exchange server that domain A is still on but this has made no difference.
We don't want to delete the database for Domain B until we are sure it is definitely not required and that all historic emails are completely moved over to the new server.
Can you advise what we need to do so that when users of Domain A send an email to Domain B the message does not stay local and goes outside of the exchange server rather than staying internal.
I believe I have found the solution in that the original mailboxes still had for Domain B still had some aliases configured that related to domain B, After removing these and sending test emails
This use case outlines the migration challenges that organizations face and how the Acronis AnyData Engine supports physical-to-physical (P2P), physical-to-virtual (P2V), virtual to physical (V2P), and cross-virtual (V2V) migration scenarios to address these challenges.
