Server disconnects after uploading each email.
I have used Thunderbird for many years. I access 4 email accounts from 3 different servers. It has worked flawlessly until recently. Now, each time I open Thunderbird , it is extremely slow to sync with any of the servers. The Activity Manager displays "The ___ server has disconnected, there may be a network problem" after each email syncs. This happens on every server. The email itself seems to sync correctly, but at a rate of about 1 per 15 seconds. I am using Windows 10 and the Thunderbird 45.8.0. Any help would be appreciated.

Windows safe mode disables anti-virus software, which is most likely the culprit. These are some generic suggestions to avoid problems with anti-virus software.
Create an exception in your anti-virus software for the Thunderbird profile folder, so that the anti-virus real-time scanner will not scan it. http://kb.mozillazine.org/Profile_folder_-_Thunderbird
Don't let your anti-virus software scan incoming and outgoing messages.
Don't let your anti-virus software scan attachments.
Don't let your anti-virus software intercept your secure connection to the server.
Remove any add-ons your anti-virus software may have installed in Thunderbird.
Keep it working. http://kb.mozillazine.org/Keep_it_working_-_Thunderbird
And last but not least, backup your Thunderbird profile on a regular basis. https://support.mozilla.org/kb/profiles-where-thunderbird-stores-user-data#w_backing-up-a-profile

I am using Windows 10 and the Thunderbird 45.8.0.
The latest release version is 60.6.1. https://www.thunderbird.net/
Why are you running an outdated (and vulnerable) version?
Thanks for the reply. Good question. I clicked on Help-about, and it said “Thunderbird is up to date”, so I didn’t check further. I’m now upgraded to 60.6.1. No improvement. I reinstalled my imap mail server account using the default settings ( no security ), but the server keeps disconnecting between each email (as far as I can tell). Also, the Activity Manager says "Bringing folder INBOX up to date" "Downloading 85 of 33 in Inbox". I can access my email from a browser and tell that there are only 33 messages in my Inbox. The 85 is still increasing slowly. Again any help or ideas are welcome. Thanks

What is your anti-virus software?
AVG is my anti-virous
Try to start Windows in safe mode with networking enabled. - Win10 https://support.microsoft.com/en-us/help/12376/windows-10-start-your-pc-in-safe-mode
Still in Windows safe mode, start Thunderbird in safe mode. - https://support.mozilla.org/kb/safe-mode
Does the problem go away?
Yes! The server stopped disconnecting and TB updated very quickly. I need to go back to normal mode and see if the problem reoccurs. Thanks.
