However, even if you always remember to close Outlook, you may have a need to open Outlook and look for certain information. Those of us who present at webinars and teach online classes, closing Outlook before the session begins is an obvious thing to do, especially when you don’t want others to be distracted by your Outlook desktop alerts (which I never enable on my computers).
Even if you are the only one who uses your computer, the search history can be exposed to the others accidentally if you are sharing your screen in a video conference and need to look up some information in Outlook. From security and privacy perspective, it’s important that you occasionally check your Outlook search history to ensure there isn’t anything in the history that you don’t want others to see. The search history in Outlook displays the previous searches that you have done to locate certain information.
