You are getting the ImapException ("Missing expected 'COPYUID' response.") because server did not respond properly to our COPY or COPY UID command. Rebex IMAP client expected the confirmation that the COPY command was OK, but actually it did not find such line within the server response.

Actually, to provide you with more information and possible solution, we again would have to see the full log of communication created via the Imap.LogWriter property. Please create it and post it here or send to support mailbox.
