So I've had Thunderbird for a few years. I've always had my (multiple) email accounts set to both check for new messages at startup, and check for new messages every 2 minutes (I keep it open in the background so I can be alerted ASAP). However since the last 2 updates, I can no longer fetch messages either every x minutes, or manually (Get Messages does nothing), and the only way to get new messages is closing and restarting TB completely, defeating the point of having it open in the background. I've tried: 1) unchecking both 'Check for new messages at startup' and 'Check for new messages every x minutes' = still can't manually pull in mail with Get Messages (the status bar says it's checking, but nothing gets pulled in unless I restart TB) 2) leaving ONLY 'Check for new messages at startup' OR 'Check for new messages every x minutes' selected = nope 3) starting and restarting both TB and my PC = nope 4) checking my antivirus isn't blocking anything = it isn't 5) checking all my email account server settings/passwords are correct = they are 6) testing out Betterbird with the same accounts and seeing if it's still an issue = this also affects Betterbird 7) checking my email accounts are working in other software like Outlook/webmail = they're fine, I can get email there normally Any ideas as to how to fix this?
