Thank you Jon/t -- very helpful. This makes complete sense now.

Then please explain why I can use other calendar apps to manage my work Outlook calendar without requiring approval and without issue.

What I mean is other calendar apps (I use a Mac) - such as macOS and iOS' native Calendar, or Fantastical - can connect to my work MS Exchange (Outlook) Calendar and read and create events without needing to ask for permission. I use those apps to manage my calendar events without problems.

How are Evernote's calendar privileges different?

Why does connecting Evernote to my Outlook / MS 365 calendar (for work) require approval from my employer?

My employer of course wouldn't approve this.

Other calendar apps can connect to calendars including MS 365 without requiring approval -- and even create events for those calendars.

Sounds like Evernote is asking for more permissions than required on the surface.
