I'm having a user with a very strange problem. After restoring his mailbox with BackupExec 2010 to Exchange 2010, he has now some mails, which aren't showing up anymore with a sender address in the "From"-field in the Inbox. When he opens the mail, he sees, who sent it.
Does anybody know something about this? Is there may be a switch like outlook /repair...? I already asked google, but there was just one having the same issue as I and he didn't get any answer.
Thanks and have a nice day
