Thunderbird not sending e-mails to my outlook.com but receiving email from Outlook IMAP works fine
To try and rectify thunderbird not sending email to my outlook.com I have deleted the acount in thunderbird twice and reset it up each time. The problem is the IMPAP e-mail download works fine but sending e-mail either stays stuck on sending, times out or I get not authenticated on SMTP server. My send set up is :- Port 587 Server name: smtp.office365.com Connection Security: STARTTLS Authentication Method: OAuth2 User name: This is my outlook e-mail address ie name@outook.com I confirmed the message originating from Outlook asking to confirm access by Thunderbird. My Thunderbird is up to date with latest version. Any Ideas? Thanks! By the way, Thunderbird works fine with my GMail account for both IMAP and Sending mail - I deleted my gmail account in Thunderbird and re-istalled it - all reinstalled work fine but not so with sending e-mails to my outlook account.
Thanks Much.

I fixed this my going to my actual Microsoft Outlook Acount and under alias names I had the primary name as my google e-mail name and changed this to my Outlook e-mail address. Alos, I went into Thunderbird Outlook account and made sure my name box contained the same name as my outlook e-mail address, as it had other outlook address consisting of my name, a long set of numbers, followed by outlook.com. Very tricky Indeed to work and try this out - took me ages.

The error message I get on sending to outlook:
"Login to server smtp.office365.com with username 'my name'@outlook.com failed"
check in outgoing server(smtp) in account settings. My guess is you have more than one outlook SMTP entry and it is using one set for something other than oauth authentication.
Hi Matt, Thanks for your reply and consideration - appreciated. Within Thunderbird when on my outlook account under the 'outgoing server', it highlights and says "smtp.office365.com". When I go into edit of this , it does list my google account outgoing server "smtp.gmail.com", but that is not highlighted - the google account outgoing server is only highlighted as active when I am in my gmail account in Thunderbird.
If Thunderbird when I am in my outlook account, is somehow using my google outgoing server in error, there is nothing to show this is happening and can only conclude some sort of bug in Thunderbird i.f that is the case. Afraid am still at a loss if anyone has other thoughts -Thanks Much
