User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.5) Gecko/20031007 Build Identifier: Thunderbird build 0.4 I have created sub-subfolders on my IMAP server, but those are not displayed by Thunderbird. Those folders are visible under the subscriptions window but not the on the folder tree. I have tried several ways for Thunderbird to display these sub-subfolders including deleting the account and readding it. :-( Reproducible: Always Steps to Reproduce: 1. Create a sub-subfolder(s) on an IMAP mail server with another mail client 2. Try to open that sub-subfolder with Thunderbird 3. Actual Results: No subfolder is displayed Expected Results: The sub-subfolder(s) should be displayed
The problem is finally resolved by deleting the ImapMail folder in the user profile.
