In my experience it's often simply expected by companys that the worker just knows this stuff because many GenX/Millenials just know their ways around that, but GenZ/Alpha are in general more knowledgeable about the functions of their smartphones than any desktop applications. It will take some time until HR departments start screening their applicants for stuff like Office knowledge (again - they used to 2 generations ago)

Is that the Outlook coming from the Intune company portal app, or a personal install from the playstore and just adding an email they let you add? Sounds terrible. Most of the work I was doing as to had it all running through Intune, so I didn't ever see that stuff. I could see how that would turn off most users. On our end just about every time security updates came out it would lock out the ability to access teams, outlook or anything until the updates were performed, and you logged back into the comp portal app to ensure the device was secure against whatever new threat there might be. So you'd have to set up confirm with 2 factors to get signed back in every couple months and require at least a pin to get into your emails.
