I'm using K-9 email with an IMAP account. When I file or delete messages from my Outlook (2007), they disappear from the K-9 inbox. I guess this makes sense with a pure sync, but my BB Storm allowed messages to stay in the inbox for weeks or months according to the settings, which was useful for me. There is no such setting in K-9 (or the native email app on the Incredible from what I can tell). Nor can either of the Android email apps allow you to add or edit the IMAP path prefix. So I don't think I can access, from the phone, the filed email messages that are now in the nested Outlook email folders. Does anyone have any suggestions?
