I am looking for a MacOS email client with two "must-have" features:
- The ability to use a dark or solarized (non-bright-white) mode for reading and possibly writing mail (like Nylas or Thunderbird), but also
- Has native Office 365 support, because my employer is cutting off IMAP/POP access to email.
Are there any clients meeting both of these criteria, whether free or paid? I've looked at Canary Mail, but it seems to fail at handling the formatting and displaying links of some very basic emails, which makes it impossible to use. (I refuse to read a solid screen full of text because my email client can't handle line breaks correctly!)
