Exmerge error: Error opening message store when trying to export a mailbox

I am trying to export some mailboxes to pst files and it's my first time using ExMerge.     The LDAP link seems to work good and I can see all of the mailboxes even though there is an LDAP error in the log, but when I go to the export I get the error.   See the log entry below.   I'm running this from the exchange server while logged in as the domain administrator so I don't see how it could be a permissions problem.

Using Windows 2003 running Exchange 2003 enterprise edition sp1

Can you access these mailboxes using Outlook when you are logged in as the account you are using to run EXMERGE?
If not then it is a permissions problem.

A domain administrator does not necessarily have the ability to access other users mailboxes by default.

The 2 articles listed by NiclasH should overcome this issue.

I tried adding the administrator to the Exchange Domain Servers group but that didn't work.
I gave the domain admin group full control of the mail store and that didn't work.
I used an account that was both a domain admin and an exchange admin and I was able to extract the mailbox.

So thanks, I didn't know that the administrator didn't have access to do that.
