I also use Mail.app privately but Thunderbird on any Windows or Linux machine I work with. Outlook might look nice, however, I can’t bring myself to spend time to figure out the calendar in Outlook. When Thunderbird was not available, I’ve defaulted to looking up my appointments on Google calendar in the browser because that’s what my team at work is using.
