I am going to recover missing this test mailbox,
I've successfully cross forest migrated few of mailboxes to target Exchange server by using ADMT with no merge.
I am facing an issue, Outlook client internal network and ActiveSync are not working with error: Outlook automatically configure failed, then "Log onto Exchange ActiveSync mail server (EAS) failed, only Outlook web is working fine.
If a mailbox created in target Exchange server (not migrated maibox) everything is working properly, including Outlook, ActiveSync.
Can anyone help me determine where the issue is for this?
Thank you in advance
