Help desk staff explain why deleting a message in Outlook on the web changes the Exchange Online mailbox. What relationship should they describe?
Select an answer to reveal the explanation.
Short Explanation
Outlook is the windshield; Exchange is the car’s trunk where the mail actually lives. Delete through the windshield and you are changing the trunk. That client-versus-service relationship is the whole help-desk teaching point.
Full Explanation
Outlook clients, including Outlook on the web, operate against mailbox data hosted by Exchange Online. Actions such as deleting messages affect the Exchange-stored mailbox rather than a permanently separate offline-only store. MS-900 expects a clear client-versus-backend-service distinction at describe depth.
