Yesterday a network drive that contained my profile went offline (no drive issues, a network one.) Thunderbird crashed. Upon restarting thunderbird, I got a new email session dialogue, and none of my old info was present. I checked the server, the files are all still there, along with a 15+ GB mail folder. I've tried the various approaches that people have posted involving creating a new profile, and migrating my imap and mail folders, etc. I've tried the profileswitcher add on, etc. None of those have seemed to work. No matter what I try, I keep getting that request to start at 0. I've copied all the mail and profile and such to my desktop machine to avoid this particular problem in future, but pointing the profile at either directory (network drive or desktop copy) is not seeming to work. Seems likely that one or more of the files was mucked up when the drive went offline. Ultimately, though, I just want to get in and get access to all my old emails (and use thunderbird to access the incoming ones.) I'm open as to what to try next? Thanks in advance for any helpful advice!
