For a few years I’m noticing more and more weird and unexplainable behaviour in Outlook. We support mostly 365 Exchange Online clients on Windows workstations or RDS environments.
The amounts of unexplainable bullshit we face is staggering. Outlook not being able to open the folder set, weird MFA glitches, weird bugs in the UI and downright weird errors coming from nowhere is some of the stuff we face weekly.
Am I alone on this?


I am just a user and not administering anything here, but holy fuck my mailbox is almost full, and yet I can’t delete more than a couple of emails at once without crashing Outlook.
I can’t believe how many wacky UI glitches this app has, and how many ways I can crash it from normal use. It’s not my PC either - coworkers have similar problems.
Do it from the web man. Doing it from the app means it needs to sync twice. Do it in the web browser, right off the server, and you can mass delete shit all day long and just minimize the browser and keep working.
