I have an IMAP email account with several sub-folders. It appears that when I click on Compact for the Trash, nothing happens. As a matter of fact, when I go into Horde mail, I see that what's in Horde's trash folder doesn't show up in Thunderbird. I had over 3500 messages in the trash on the server, yet Thunderbird only shows about 24 at this time.
Any ideas why?
