Scheduling and managing events using Outlook.com calendar
Hi Pearl,
As per checking, the Family Room calendar hasn’t been deleted. Microsoft recently changed how family calendars work in Outlook.com. Instead of showing up in the usual calendar list, they are now found under Groups.
As a workaround, from Outlook.com and open the Groups section in the left menu. On the Outlook mobile app, you’ll also find it under Groups. Once you locate it, you can add it back to Favorites so it’s easier to access.
