Hi

Can you fail the database over to server 2 and then try move mailboxes?

Hi thanks for the reply . I kinda panicked there for a second lots of troubles the last few days fresh cup of coffe and some fresh air.And i dismounted the database restarted the isexchange service and mounted it again it did  the trick .  

Hi,

Thanks for your response. It's great to hear the good news.

The Microsoft Exchange replication service is responsible for the mailbox migration. Sometimes restarting this service can solve the mailbox migration issue.

Hope this can be helpful to you.

Best regards,
