I ask because the Default Account designation is stored in the prefs.js file, located in your Profile. If one preference is not sticking, I would expect to see other properties not sticking, either. </p><p>First thing to try is to restart Thunderbird in Troubleshooting Mode. Go to menu item <Help | Troubleshoot Mode...>. Let it temporarily, not permanently, disable all your add-ons. After it restarts, try changing the default account again. If it's successful, that could indicate a misbehaving add-on. </p><p>Please let us know the results. If that doesn't do it there are some other things to try. </p>",rednoise,false,0,0

I get the normal log in screens to add permission with oauth2, signed into yahoo account in yahoo and it shows thunderbird has access, yet Thunderbird still can NOT access yahoo mail (download pop or send smpt).
