It won't find or download any email collected from a mobile device such as a Treo.
I checked my messages on my Treo this morning, found that I had two...this is the first time checking mail on my Treo since I've been using Thunderbird. When I went to download them in Thunderbird they didn't show up. There wasn't any indication they were there. I knew they were so I clicked the "get mail" button. Nothing. I went to Outlook Express and they downloaded.
I couldn't find any kind of an option in Thunderbird that would solve this.
