Hi, my PC runs windows 10 and thunderbird loads but then that's it there is next to zero operation, no get new messages, just locked🤔 All settings are the same as K9 on my phone and email works there. I uninstalled and reinstalled thunderbird but that altered nothing. Antivirus and security are normal and trouble shooting says nup so I'm lost🤷 I have a modest knowledge in regards to this and all ' advice ' online has had zero impact. Any help much appreciated thanks Mark B
