If you use Microsoft Teams, the Calendar application is a central component to keep you organized in your day-to-day activities and there is nothing more frustrating than seeing an error message that prevents you from seeing your schedule.

If your calendar is presenting you with the error message “Couldn’t load your calendar. Let’s give it another try” there is one thing you can do before reaching directly to your Microsoft Teams administrator.
