Yesterday, downloading emails got stuck because it couldn't download an email. I tried this multiple times and then it said it couldn't connect to my email server. I tried Repairing the individuals folders but the problem persisted. I looked the problem up, and one of the recommendations was to uninstall Thunderbird, the profile folder, and install it again. When I launched it again, it told me it couldn't find a profile, so I went to the app data folder and restored the folder containing my emails etc. I reconnected it to my Yahoo Mail server. I started TB this morning, and it does the same thing. It tries to download 205 emails, when I know I haven't got that many from yesterday. It still gets stuck on email 21, so I close it, open it, close it, open it, in which it checks again, and I go round and round in circles. It is now telling me that it has failed to connect to the Yahoo server. Checking mail through the Yahoo site works fine. I am using TB 149.0.1 on Wiindows 11.
