I used to use Evolution until MAPI was removed, then Thunderbird+Exquilla for a bit, but now Thunderbird+IMAP is the sensible way to go. I make all my email rules server-side using OWA, and Thunderbird has had most of the OAUTH2 growing pains sorted out for a while now.<p>We use Teams, which handles all the calendar stuff I used to need my mail client to do for me. The only risk seems to be Microsoft silently changing something and Thunderbird being left to figure out what to fix. I no longer need to access proprietary Public Folders, as that functionality has been swallowed up by Sharepoint Online.<p>I've used Linux at work for the past decade, in spite of it being a Microsoft shop -- some days I would wrestle with HyperV or whatever ricketysticks thing Microsoft bolted on top of HyperV, some other rare days I'd get to play in the terminal all day.<p>I could tolerate using Windows if I was forced to. But I absolutely love using Linux. Who even needs Outlook specifically these days?
