It seems that the mail you had in Thunderbird is gone so at this point I would open your address book in Thunderbird and use the tools > option choice to export your address book. I would then use the Revo Uninstaller (free if you don't have it) at it's highest setting and unintall Thunderbird then download the newest version and install it and set up your account again. You could then import your address book from the file you saved. If you go to att.net and check your mail there you may find that much of it is still there. It depends on your settings in Thunderbird.

I guess Thunderbird is looking for Outlook Express which is no longer around. Have you tried double clicking on the .wab file to see if the windows mail program will open it? Whatever version of windows mail is included with Win 7 should open the file and then you should be able to export it as a csv file. If double clicking doesn't open it try right clicking on it and then click open with and see if some mail program is on the list.

I found it... In thunderbird click on view. Then click on read message body as. Then set to read message as original html. I had changed it to read message as simple html. That was the problem. Thanks

It IS a very strange situation, indeed. And here's some more weirdness. None of the e-mails stay on the server...I double checked and everything was downloaded, per the settings. When I first started looking for a prog to replace WLM, I started using Outlook....but the e-mails were disappearing from the Inbox. I thought it was a problem with Outlook and even posted a query here on the forum. Never solved that issue, but disliking WLM more as time went on, I gave up on Outlook and thought I'd try Thunderbird. Then the same thing started happening! I had made TB the default and set WLM to NOT check automatically for mail....BUT...when I would open WLM to look at something in a folder there, it would check for mail on Startup and all my e-mails would show up. That's when all the messages in TB would disappear. When I realized this was happening, I opened Outlook, sent some test messages there and watched as they disappeared before my eyes when I opened WLM. Do you think maybe I'm incorrect about the mail staying on the server? Wouldn't I see it there when I go online to check?
