Fix getting repeated "server disconnect" error messages.
Towards the end of the business day, or whenever trying to compact folders, Thunderbird disconnects with the error message, "Server imap.[...].com has disconnected. The server may have gone down or there may be a network problem." Neither seems to be the case. Reloading software did not work.
Chosen solution
Compacting folders is an actions that sees Thunderbird creating quite large files (right click your inbox select properties. What size is it on inbox?)
Then you say towards the end of the day you also see the issue. Is there a local backup or other disk intensive activity that occurs at that time each day? (Windows defrag is schedules in on windows 10 machines these days)
I found that Windows search scanning and defrag both affected Thunderbird detrimentally and I disabled both occurring automatically on my profile folders.
