protocol error when syncing with exchange 2007

["Simon P. Ditner" <simon-oi@xxxxxx>]

Hi,

I'm running into a problem when syncing with an Exchange 2007 server; it 
kind of sounds like the message is being deleted by another IMAP client 
at the same time that I'm attempting to sync it. Anyone else run into 
something similar? (offlineimap 6.0.0)

Thread 'Folder sync Acct_3[INBOX]' terminated with exception:
