I'm having the same problem as propatho. &nbsp;This is the second Exchange 2007 installation, although this one is in another site. &nbsp;I was able to move one former employee's mailbox, but when I try to move any current employee I receive the same error message. <br />
<br />
Further testing: on the 1st Exchange server I'm able to move a disabled users mailbox from Exchange 2000 server to the 1st Exchange 2007 server. &nbsp;I'm reviewing permissions on both exchange servers hoping there is an rights issue.

One of our issues is that we have an in house app that adds users to AD / Exchange.<br />
Hhowever, one of the follwing actions which I performed has resolved the &nbsp;problem:<br />
<br />
Unhide from GAL.<br />
Check that user is NOT disabled.<br />
Check all permissions against an account that has succesfully been migrated.<br />
<br />
Worked for me..<br />
<br />
Good luck,<br />
