Please verify the answer, if it helps to resolve your issue.
If you want your Windows login to login NAV, you may set the user credentials as Windows authentication. So once you are logged into the computer system, you can use NAV without entering a user id and password (it will use the currently logged in windows USER).
Are you looking for single sign-on with Windows and NAV or single sign-on with Office365, Windows and NAV?
Oops, forgot to include link:
(single sign on with O365)
