The account setup and calendar are the cruftiest parts of Thunderbird for me. The team brought fantastic changes to the mail view. I’m excited to see what you’re cooking for the Calendar view!

in reply to Thunderbird: Free Your Inbox • • •@uriel fantastic! Happy New Year to the team and folks working on this. I really hope we can choose Thunderbird instead of Outlook on Microsoft-driven IT! This makes it possible! I’ll test it on my device and report back!

I can authenticate successfully, but the Redirect URI urn:ietf:wg:oauth:2.0:oob is not closing the window after this and the account doesn't sync after this.
