Do you mean you just hit Delete, or that you hit Delete and then
Expunge? I would expect Delete (i.e. "mark as deleted") to be cached and
therefore succeed temporarily. The next server synch should then fail
because of the permissions problem. I would expect Expunge to cause such
a synch and failure. If *at that point* it appeared to succeed then that
would be a problem.

That sounds OK so far.

That's a good question. I occasionally want to tell Evo to just forget
its local state and forceably resynch a folder with the server (e.g.
when the Unread count doesn't match the number of Unread messages).
There doesn't appear to be a way to guarantee that short of
unsubscribing the folder, exiting Evo, restarting it and re-subscribing
the folder, which is ridiculous.
