80004005 Thunderbird



I was connected to O365 with my work email but cannot send any message. IMAP works just fine, all folders synced regularly, but sending not work for some unknown reason.

  • Thunderbird Bra; Tools; Top Hoist; Trailer Tie Downs; Air Conditioning & Heating. Air Conditioner Kits; Blower Motors & Wiring; Compressors, Condensors & Driers; Dash Knobs & Bezels; Fan Belts, A/C Hoses, Heater Hose & Fresh Air Ducts; Fresh Air Systems; Heater Core, Gaskets & Valves; Vacuum Canister; Body, Sheet Metal & Frame.
  • Start Thunderbird in Safe Mode & Fix Thunderbird Problems or Errors. To troubleshoot any persisting Mozilla Thunderbird email issues, a user can start the Thunderbird in the Safe Mode. It is because a user can change the Thunderbird settings in the safe mode. If required, one can disable add-ons also, which creates Thunderbird issues.

SMTP setting is as follow:smtp.office365.comport 587STARTTLSOAuth (this is correct setting, all others shows errors, including outlook.partner.cn & smtp.office365.cn, which is completely normal since I'm not in China).

One of my users has a problem not being able to import ICS, everytime she clicks on Thunderbird to import a ICS file she receives: Processing message failed. Status: 80004005. Now I am not 100% sure WHERE this happens but considering that the calendar in Thunderbird uses the following link to add the entry to SuiteCRM. Ich habe heute ebenfalls mehrfach versucht aus einem Portable Thunderbird (1.5.0.x) einen Thunderbird Portable 2.0.0.9 (Deutsch) zu machen, aber auch ich bekomme nur einen leeren Screen und die oben beschriebene Fehlermeldung. Das Adressbuch scheint allerdings zu funktionieren, so dass das Update wohl teilweise funktioniert haben muss.

The first thing that jump out is that my password is not OK, which is not correct. Password is OK. Click on 'Retry' or 'Enter new password' do nothing, just return the same pop up. If 'Cancel', then receiving message with 'unknown error 80004005' and all other blablabla about unknown reasons, with instruction to check my SMTP settings.

I've tried all variations available, but nothing works. Sometimes, at some moment after click on Cancel, it said 'Message sent' and I can see it in my Sent Items folder, but it's fake because I never receive that test message to my personal Gmail address.

I have already tried all suggestions I could find (deleting passwords, resetting all, restarting, deleting and adding account again, changes in Config editor related to security.tls), but nothing worked for me.
