Thunderbird/Gmail won't SEND messages with any attachments
Gmail Minetfiber.com Windows Defender (OFF) Anti-virus (OFF) Windows 10 Thunderbird 60.7.2 32bit
I get "unknown reason" or, sometimes, "timed-out" error messages.
Additional System Details
- User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:67.0) Gecko/20100101 Firefox/67.0
I should have added that I was unable to include a screen shot of my Account Settings, the "Add Images" button below just wouldn't work.
And I've spent about 6 hours trying every variation of fix that I could find on the web, except changing the Password. I deleted and setup new Thunderbird accounts with the automatic settings twice; changed the Ports/Authentication/etc. to every possible combination and a bunch of things I've forgotten besides those listed in the original message.
Thanks for any help you can provide,
Killer Control Center has to be updated to match Windows 10 update to fix this. Why it interferes, I have no idea.
