Thunderbird for Mac and new security settings OAuth2
I have changed as request by microsoft server income and smtp with OAuth2 but sending doesn’t go and automatic pop up says I must use STARTTLS…. I don’t understand how to set.. M.
When configuring IMAP/SMTP in Thunderbird, select OAuth2 authentication and authorize with a Microsoft account. However, this requires Thunderbird version 91 or later.
