Hey all. A while ago we upgraded from Exchange 2003 to Exchange 2010. I have to restore a Mailbox from last year, when we had 2003. I brought up the original 2003 server because we still had it, it was just turned off. I was able to create the RSG and restore to it. The problem is that when I use Exmerge I receive this error message: Error opening message store (MSEMS). Verify that the microsoft exchange Information store service is running and that you have the correct permissions to log on. (0x8004011d).
Now im aware that this should be a permissions issue. So I created a new account and gave it domain admin rights. I delegated Exchange Full Admin rights to it. Then at the top level I added the new account with allowing everything, even the send and receive permissions. The domain admin group as well has Allow for all permissions, even the send and receive. After Irestarting the services, that "should" have been enough to gain access to it, although I still cannot. I even tried logging in with my user account which is a domain admin account and tried creating a PST from my mailbox account in the RSG, and could not either.
How can I create this PST, any ideas? Like I said, this server has been turned off since the upgrade to Exchange 2010, and Im thinking our upgrade could be have an influence on our problem. Its not like I can restore from the RSG to the Information store on 2003 because all mailboxes are moved over, and this user account that i want to export to a PST was deleted when he was terminated a while ago.
