All of my e-mail uses the IMAP4 protocol. I synch about 40 folders altoghether. Having to purge each folder individually is a pain. I usually hide the deleted messages as I find the struck-through grey text distracting.

What I would like is to automate purging my IMAP folders, similar to how you can automate archiving folders. Is there any way to do this in Outlook or with an add-on application?

Or, is there at least someway to purge multiple IMAP folders at the same time?

This is another area were Mozilla Thunderbird beats Outlook when using IMAP accounts.
