I figured TB was currupt. I decided to uninstal TB. Usually TB is downloaded from the Mozilla TB site. was necessary to download TB from the microsoft store, which caused me to lose my 300 addressbook contacts and the recovery address book service would not work allthough I received the message the address book was found on the server. Again the messages were not displaying at all in the all or inbox, or important folders which gave me the idea to uninstal and reinstal. I think the program is pretty straight forward, but maybe I wasn't clear about the messages not displaying in the all or inbox folder, that may be important.
