Managing personal Outlook.com account settings, security, and privacy
Hi, I'm John! I will help you with this.
To help narrow down the issue:
- Are you getting the "Access Denied" message in the Outlook app or on Outlook.com in your browser? Also, what exactly does the full error message say?
- Are you using a personal Outlook account or a work/school account?
For a quick test, try opening Outlook in a private/incognito browser window and sign in there. Also try another browser if possible.
If possible please capture a screenshot and attach it in your next response. Thanks :)
