Has anyone encountered this issue and if so what did you do to resolve it? Users periodically have to sign into Outlook several times a day. Message received "You don't have access to this. Your sign-in was successful but you don't have permission to access this resource. Sign out and sign in with a different account." Occurs with Outlook 2016 versions 16.22, 16.23 and 16.24. Happens most of the time while they're in the middle of using Outlook; or waking system up from Sleep mode; other times after launching Outlook for the first time of the day.

+15I've encountered that message if a user runs out of O365 licenses, or they've recently changed their password and something is messed up with the keychain. For the keychain-based cause, removing all Microsoft/Office items from the user's keychain (or just creating a new keychain) resolved the issue.
