For the next several weeks (and months?) I'm evaluating at least a dozen open source and commercial #email apps.
Now, I'm honestly not saying this because I work at @thunderbird, but the new #Outlook is a buggy mess within the first 5 minutes of use. I'm quite surprised that "Switch to New Outlook" toggle is even there.
My Gmail account requested re-authorization twice, and switching off Focused Inbox completely zapped everything from the message pane, and I can't get it back.
@thunderbird I WILL give #Outlook some praise though: I'm a fan of those colored icons on the horizontal ribbon. (Just not a fan of the ribbon itself...)
@killyourfm @thunderbird Yep, a big usability #fail by Apple & Microsoft in recent years is forcing borderless buttons, all the same shape, even monochrome. Colours & shapes help me identify & remember what is where.
There used to be an app to bring shaped buttons back to OS X Mail.app: "CageFighter"
