Mozilla has done it again. Thunderbird now has PIM functions! Granted it’s still in super mega infant alpha stage 0.0.1 but I now can store my tasks and notes within Thunderbird. Check out Lightning, Thunderbirds latest addition that will put it on stage with Outlook and Evolution. Get the latest version here! Oh, and listen to their advice and use Mozilla Backup.
I was having problems with Mozilla Thunderbird where my inbox was slow to load and it kept bringing back deleted emails (the same group of emails kept returning everytime I restarted Thunderbird. After reading a post on the Mozilla forums I moved all emails that I wanted to keep and all folders that were in the Inbox into a new folder, then I quit Thunderbird, deleted Inbox.sbd, Inbox and Inbox.msf in the thunderbird root folder and restarted it again. Everything is working great now. I would guess that the inbox files/folders got corrupted.
