That's great. Now do one on why Microsoft Teams grinds away with 100% CPU on my laptop for a few minutes just to bring up my calendar, or why Outlook on Android freezes for a minute or so when looking at a single small email.
I wish my company would use something else but the CIO is hellbent on “rEdUcInG tHe nUmBeR oF tOoLs” and MS was apparently throwing in teams for “free” as part of o365 sub.
Teams uses Active Directory, and they can argue it's "good enough".
