Hello guys, I am in critical situation with exchange 2010. I have 12 problematic users in my exchange 2010 server. There is no DAG. Just one exchange 2010 server with all roles. So I need to remove that users and Mailboxes from exchange and recreate. After that I need to restore all emails to newly created users. Username and password will be same. Please advise on this issue. Iam highly appreciate if you can give me steps. Regards

Run the following command: Export-Mailbox -Identity <username> -PSTFolderPath <path>.pst If you get a permissions error use this to gain export rights New-ManagementRoleAssignment –Role “Mailbox Import Export” –User “<username>” This will give you both users one at a time in .pst format which you can reverse the commands to import with.

After exporting the data and deleting mailbox, you can run clean up the mailbox from exchange box. After purging mailbox wait for some time and create new mailbox with same email address as well as alias SMTP without any issue. To clean up the mailbox, please refer to the following article: http://technet.microsoft.com/en-us/library/bb124076.aspx Thanks.Novak Wu-MSFT
