Thunderbird-Hilfeforum

I was able to send emails till July 14. After that day it's been impossible to send or reply to messages from my Outlook account (I receive emails though). I have made no changes to Thunderbird's configuration since then. Basically it's the Oauth2 authentication that fails. I briefly see a browser page for authentication, wait, wait, wait and then the mail is not sent and I get an error message related to servers timeout (attached). Sorry, my interface is in Italian, but anyway the message is something like: "Unable to send email because of a timeout on the connection to the out server (SMTP) smtp.office365.com. Try again." Is this a known bug? Any ideas? It's quite annoying to use the browser interface to send messages while I am able to receive them in Thunderbird :) Thank you in advance, guys!

I recently installed the Flatpak version of Thunderbird Version 115.0.1.

I can no longer start Thunderbird from the command line. It is supposed to run by using the command flatpak run org.mozilla.Thunderbird. When I issue this command nothing happens.

I can however start Thunderbird by using rofi. When I use rofi to start Flatpak Thunderbird, it runs perfectly.

I do not have any problems with any of the other Flatpak applications that I have on my system. Prior to updating Thunderbird, I did not have any problems with the Flatpak version of Thunderbird that I had installed. It is just this new version of Flatpak Thunderbird that is giving me problems.

I am running Debian Linux version 12.
