Hi!

I have a problem when migrating to exchange 2013 that some users need to repair their outlook for it to realize that the mailbox is moved to a new database, for some, it works right away after a restart of outlook and for some it takes time and for others they need to repair their outlook.

What happens:

1. Mailbox is migrated
2. Outlook notifies user that administrator have made changes, "please restart outlook"
3. After restart, Outlook says, "connected to microsoft exchange" but can't send or receive emails.
4. In account settings -> Server settings. the old CAS-array is still specified as server, not the "GUID"-server.

Autodiscover works when testing outlook connectivity.

I have no idea why it works for some but not for others! Any ideas ?

Exchange server 2013 Cu8 on Server 2012 R2

Thanks!

Hi,

Since the issue only happens to some users instead of all users, it indicates that the connection services in Exchange 2013 side should be correct. We can narrow down the issue to the client side. Please upgrade your Outlook client to the latest version to have a try:
