okay, then I think I got it right.

The difference within Kolab is that the objects are lying seperated in
different IMAP folders. Getting an event based on ID always acts
within the confines of one single IMAP folder. So even if there are
other folders holding an object with the same ID there should be no
problem.

If we do a UID search in the kolab driver this is limited to the users
personal IMAP folders.

Cheers,

Gunnar
