Thunderbird-Hilfeforum

I've been a faithful Thunderbird user since the beginning - and continue to use Thunderbird with our company's Microsoft365 deployment

until Monday of this week -- when suddenly I find that my credentials are being refused.

The symptoms

• XXX: Connected to outlook.office365.com
• nothing in the activity viewer
• no email coming in

I've read and tried all the fixes proposed in the article at https://support.mozilla.org/en-US/kb/microsoft-oauth-authentication-and-thunderbird-202 (restarting thunderbird after each step, naturally)

• have authorized Thunderbird to our Microsoft365 tenant
• created and tried registering with a new thunderbird profile
• have set my security settings to 'accept all cookies'
• have used the config editor to remove 'oauth2.issuer' and 'oauth2.scope' values
• I've checked that my account in Microsoft365 has IMAP and Authenticated SMTP enabled

So, since Monday, I've been living in hell, trying to pretend that the Microsoft Outlook app for macOS is useable, but it's practically debilitating to be forced to use that piece of software.

Can somebody please point me to another possible set of steps that I can use to try and diagnose this?

I absolutely hate myself for having to ask for help on this, but I'm at my wit's end...

After moving my thunderbird 104 profile to 115 supernova (including the profiles.ini file), I can see the full list of accounts and folders in supernova, but none of the emails are visible. I can receive and send new messages, but again - none of them are visible when I want to see them later in the inbox or sent folders. Moreover, the right-click mouse button does not work on the whole list of accounts/folders on the left side of the agent. What to do. I have 16Gb of emails and cannot use them.

When trying to sign messages with thunderbir on debian mails won't deliver.

If they are not signed, it will send smoothly even if they are encrypted.

for about a month now I have not been able to download mail on Thunderbird for the Gmail account Configuration: imap.gmail.com port 993 SSL/TLS Oauth2 I have double authentication, the confirmation request appears on my smartphone, I confirm, insert the password on Thunderbird, accept the conditions and get the error. I also tried to change the password (on Firefox and Chrome I log in regularly, on smartphones too), with Thunderbird 102.13.0 32 bit on windows 11 no.... Below are the screenshots
