Hopefully this will be automatically translated or does it have to be set up in English while I see everything here in my own language Dutch? Use Thunderbird is on hold because every time I start this I keep getting error messages, starting with: "Login to server imap.proximus.be failed". I then enter my password every time; I get the same message again, only to log in the 3rd time and download my mails! It is annoying that thunderbird does not recognise me and my data on my personal pc windows 10. I checked all the settings several times and compared them to the ones proximus gives. So now I only use Thunderbird as a kind of backup: a real shame because it is much more than that. Use version 91.4.0 (64-bit) and is up to date. I hope to receive answers, thank you.

Next, state the other apps that might be affecting TB, e.g. antivirus, password managers, VPN etc. A good way to test the effect of startup apps is to run Windows in safe mode. Check Saved Passwords in Preferences and remove any obsolete entries. If you remove all of them, then restart TB, you will be prompted for the password, and can check the box to have it stored in Saved Passwords.

Bedankt voor je hulp. Alles gecheckt maar vooraleer over te schakelen naar veilige modus ging ik de wachtwoorden in firefox controleren en daarin stond het wachtwoord met een andere alias. Denk dat dit probleem nu opgelost is want zie voorlopig geen vraag naar wachtwoord meer. Bedankt.
