Hello!
Just to clarify, Outlook 2013 pulls profile details from your Microsoft account, not from the local Outlook profile. Files and messages appear because your Microsoft account connects to services like Outlook.com and OneDrive. Removing OneDrive or recreating the Outlook profile does not change profile data.
To remove visible data, sign in at account.microsoft.com Open Privacy. Review activity history and stored content. Delete unwanted items from Outlook.com and OneDrive. Allow time for sync across Microsoft services.
