Article in English: The Outlook icon looks like an "O" and an envelope. You can find it in your Applications folder. This button is located next to Window on your menu bar at the top of your screen. It will open a drop-down menu. This will open the Microsoft AutoUpdate wizard in a new pop-up window. This option will allow you to check for updates manually without scheduling automatic update checks. Alternatively, you can select Automatically here, and select Daily, Weekly, or Monthly. This way, Outlook will automatically check for new updates in the future. This button is in the lower-right corner of the AutoUpdate window. It will check if there's an available update.  If Outlook finds an available update, you'll be prompted to install or skip it. If there are no available updates, you'll get a pop-up notification. Click OK to close it.
