601087 - Moving (not copying) folders from IMAP account to different IMAP account keeps original folder there

Status: RESOLVED INVALID

(MailNews Core :: Networking: IMAP, defect)

I typically don't enable "local copy" but recently I gave it a try in order to speed-up reading of emails.
Now I'm trying to move some folders to another IMAP account and, while previously - when the local copy was not enabled - the source folder would be removed after the "move" operation, now the source folder stays after the move operation completes. So it's acting more like a copy than a move...

Reproducible: Always

Steps to Reproduce:
1. configure two IMAP accounts
2. make sure that "local copy" option (ie keep messages on this computer) is enabled and that folder to be moved is selected for offline use
3. move folder to second IMAP account (drag & drop)
Actual Results:  
folder is copied to second IMAP account but a copy is left on the first IMAP account (instead of "moving" it, therefore removing the source afterwards)

Expected Results:  
source folder should be removed after completion of "move" operation

I'm pretty sure that it only happens when "local copy" is enabled as previously - with this option disabled - I don't remember it happening...

Can you reproduce and log ImapAutosync when you do this ? (see https://wiki.mozilla.org/MailNews:Logging)

sorry, let me rephrase this a little:
the things I was sure about (and I just double-checked) is that when moving *messages* from a folder on an IMAP account to another folder on a different IMAP account, TB actually does a "move", that is copies the message and then deletes the original one.
but this doesn't work if I try to "move" a whole folder, in that it just copies it and leaves the original one there.
is this per design or should the "folder moving" action be consistent with the "message moving" one? (I suppose it should)

folder drag across accounts defaults to copy, because it's a little too easy for some users to accidentally drag folders, and cross-account move/copies are expensive. But you can hold down the shift key to make a cross-account folder drag do a move.

so invalid, unless shift+drag isn't doing a move for you.
