Using New Outlook on Windows for professional communication and productivity
Log into the web based version and sign out of your account from the right upper corner.
This did not work for me. I logged out of my outlook.com web version, and I was still able to reach my mail in the New Outlook. (Win 11)
Like others, I desire a simple log out and sign in. This seems to be something only Microsoft can provide. I wish they would do so and add the sign out/in process that the webmail uses.
