The primary reason I hated Thunderbird, was because it would always drop authentication whenever I tried sending e-mail from my Outlook address. Yeah I can see mail coming in for my Outlook e-mail, but I also wanted to send too and I always had to go over to Outlook and deal with the awful and confusing UI to send mail.

I had just tested BetterBird’s capability by sending an e-mail from my Outlook address to one of my GMails and no issues. So, fuck Thunderbird.
