For a couple of months now I have not been able to keep the email client logged into my email account. Every so often I have needed to re-enter my email password in download my emails. However, this does not happen with my email on my Apple iphone, it functions normally. Last year, I added a laptop email using Thunderbird and it also is now having this issue starting about the same time as my desktop. I did not have any issues with my email until several weeks ago and it happens on both computers. I asked here what to check, and followed the instructions given here, still no change. In fact, on my desktop, it no longer will download any emails, no matter how many times I enter my password. I use the desktop for my regular email use, with the laptop used for when I travel. The iPhone is mostly as notification of emails so I can answer on my desktop. Let me repeat, everything has worked well and without issues until a few weeks ago. I made no changes in my settings prior to that, no changes to my internet provider, no other changes than normal software updates to Thunderbird. Thank you for your past guidance and for future help.
