Thunderbird and GMail keep losing Sync

Thunderbird Connectivity

My wife has been using Thunderbird for Years

Our email provider went to GMAIL about 2 years ago and we set up TBird to connect as per their instructions. 

It has been working perfectly until recently.

What happens is it seems the two lose sync with each other. No emails come in, and when sending one out, we get an error saying it can't be put in the sent file due to a network error. Also when deleting emails they are not deleted from the gmail account, only TBird The only temporary fix is to delete the gmail account and re-install. This gets it going again but all the emails that were deleted come back in from GMail and we have to delete them all again. I have to do this every couple of days or sometimes it goes a week and it's a pain. We also get a certificate error that has something to do with port 993. Sorry, didn't get a screen shot. Have the latest Thunderbird on the PC as well. It's running Windows 7, I know it's badly out of date, but could that be the problem? Some people are hard to convince to change things Has anyone seen or heard of this happening.

The problem is almost certainly your antivirus program. Prevent it from scanning email and encrypted connections on Port 993. That will probably make a 100% improvement. Personally I use Windows defender largely because it does not even pretend there is some benefit is scanning incoming email.
