My company just started requiring Microsoft Intune Company Portal app to use Teams and Outlook. From a friend in IT infosec at another company said the app can push apps, require certain settings, password requirements, or OSs, and can see a lot of stuff on your phone. I don’t think this level of intrusion into my personal phone is warranted or ethical. Be warned. I’m just going to uninstall and suffer the internal political consequences.
100% right decision to get a secondary phone if you have to do this, IMO. It may not break at the same time, you can leave it somewhere and still use your main phone, your phone decisions are separate from your work considerations. Some new secondary phones look really cool also, like the one with the BlackBerry keyboard.
