Outlook for Mac is surprisingly good, though. Every interaction feels (and is) native.

Kudos to the team. I think this is same team that maintains Office Suite for Mac.

I hope to see Teams for Mac in the future. Current Teams app is dogshit.

Surprisingly good is a stretch. Barley adequate more like it.

Now that they've hidden mail access behind oauth (imap and SMTP, additionally SMTP behind global default off policy) and graph api behind oauth2 - it looks like they don't have to worry about real mail clients competing.

Actually fighting [f] to get mail in/out working with freescout right now - and having had learn more than I care to about o365 and PowerShell etc - I wonder how hard it would be to write a couple of stand alone tools to get fetch/send/sync mail working with o365 and local maildir - to get my/sup/any sane Mua to really work with o365/exchange/outlook.

Then there's calendar and teams to deal with..

[f] Thankfully our o365 reseller does most of the fighting - I'm happy to not have tenant-wide admin in AD/entra/whatever kerberized LDAP is called today.

Are we talking about the same Outlook here? And I mean that sincerely. I just joined a new company and now have to use MS software for the first time since Windows 7. Outlook, Teams, OneDrive, you name it, are all a clunky mess (at least on MacOs).
