We have an exchange 2003 server. Have two mailstores. Mailstore 1 - old store with everyone and Mailstore 2 - new that we are migrating folks over to. Problem: mailstore 1 is now gone. No recovery/no backup. Exchange server has been unstable and we have been moving folks to new mailstore. All my clients are outlook 2010 cached exchange mode. I have their .ost files and can convert to .pst. Problem after logging back in Outlook askes them to use a temporary location for mail (obiviously no mailbox) so we do. We have imported the cached psts into the new account. We then went to users and exchange tasks and moved the users mailbox to store 2. Everything seems to be worKing BUT the new mailstore doesnt show the mailbox with the alias. What is the best way to rebuild the mailboxes with the .ost file. Otherwise years of email are gone.
Any help would be appreciated.
