I've used Thunderbird for years. This week it's started to die. First I thought I had too many emails, so I did a massive amount of archiving and compacting. What happens is that I click 'get messages' I see that it connects to my pop server, but doesn't come back with new messages. My mobile devices and web based mail from roadrunner retrieve and send email fine so I know it's not my account. Anyway I re-installed Thunderbird thinking maybe I have a corrupted file someplace and initially - success. Mail gets retrieved - just 1 time. Then it won't retrieve email again :( No settings have been changed. I upgraded to Win 10 from Win 7 over 30 days ago.. so I don't think it's Win 10 related a this issue only started recently. Help! I hate to consider giving up Thunderbird for this issue.
