Question
How do I find my Calendar in the Office 365 Portal?
Answer
Login to portal.office.com with your Sierra College email address and password.
Click the 9-dot "app launcher" icon as shown below, then click on More apps. (The app launcher icon is located at the top of you screen, toward the left.)
Most commonly used applications will be displayed, but if you don't see Calendar, click on More apps at the bottom of the window:

From the More Apps menu, locate Calendar. You can also locate your calendar in Outlook.
