Reinstalled TB and now it can't see any of my email addresses and will not let me add any.
Thunderbird first began to be Unable to log onto some of my email accounts. When I tried to add these back to TB, it would not let me add any accounts. With two important accounts remaining, I backed up my profile (for safety) and downloaded and reinstalled TB. Now the new installation cannot log onto my two accounts and will not let me add any accounts. I replace my profile with the backup but nothing changed. I've tried all the solutions I could find on the web without results (tried adding manually, adding off line) (Windows 10 with current update) (Any helpful emails would have to be sent to my phone at tedurham@me.com since I cannot receive PC emails)
