User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:103.0) Gecko/20100101 Firefox/103.0

Steps to reproduce:

Tools\Account Settings\Server Settings\Check New Messages

Setting has been 1 Minute (for all previous T-Bird releases). Version 102.1.2 seems to be irregular in checking or doesn't check at all. I have to click "Get Messages" to have emails downloaded.

Actual results:

Messages have been sitting on server for an hour. I have tried unchecking the check mail options. Closed out program and restarted. Activated 1 minute interval and same irregular behavior occurs.

Expected results:

T-Bird should automatically contact server every minute and download new emails.

I suspect you're seeing bug 1779306. After a network error it's not resuming scheduled downloads. Will be fixed in 102 soon.
