Frequently Asked Questions

Why did my Microsoft Teams calendar disappear?

The Microsoft Teams calendar relies entirely on Exchange Online to function. If your Exchange Online Plan 1 is missing, disabled, or expired, the calendar tab will automatically vanish from the Teams application.

How often do I need to verify my Microsoft 365 A1 educational eligibility?

Educational institutions and users are typically required to verify their academic status annually or at the end of their standard subscription term to maintain free access to the A1 plans.

Can a standard user check if Exchange Online is enabled?

Yes. Standard users can view their active licenses by logging into their Microsoft 365 portal, navigating to 'My Account', and selecting 'Subscriptions'. However, only an administrator can restore or reassign the missing Exchange Online Plan 1.
