User complained that IMAP moves seems to work "locally" but not on the
server, WA still shows the mails in the original folder. Took me while to
figure out that this seems to be a problem of WA, not IMAP: IMAP copies and
then marks deleted, and only later "expunges". While the mails are still
there, but marked deleted GroupWise Client shows them crossed out; WA does
not indicate in any way that these mails shouldn't be really there any

Is there something wrong with our WA, or is this just the way it works?
Works as designed or bug?
