Using New Outlook on Windows for professional communication and productivity
Hi, I'm Diane and I'm happy to help you today.
"This account is not supported in Outlook for Windows due to the license provided by your work or school. Try to login with another account or go to Outlook on the web"
The affected account is from a different organization than the one you can add? Admins can block the use of the new Outlook app.
Let us know how it goes, we're here to help you further if needed.
