Solution 1Recommended

Open a Support Request via Microsoft 365 Admin Center

Because Bookings calendars are tied to underlying Exchange mailboxes and Microsoft 365 Groups, a global administrator must investigate the tenant to recover deleted data.

Microsoft Bookings stores its calendar data in a hidden scheduling mailbox within Exchange Online. If the associated Microsoft 365 group was accidentally deleted, the calendar will disappear. An administrator can recover this group if it was deleted within the last 30 days.

1
Log into the Admin Center

Sign in to the Microsoft 365 admin center (admin.microsoft.com) using your administrator credentials.

2
Check Deleted Groups

Navigate to 'Teams & groups' > 'Deleted groups'. If you see the group matching your missing Bookings calendar, select it and click 'Restore group'.

3
Submit a Support Ticket

If the group is not listed, click on the 'Support' or 'Help & support' icon at the bottom right of the admin center screen.

4
Provide Calendar Details

Type 'Missing Bookings Calendar', select 'Contact Support', and provide the exact name and email address of the missing calendar to the Microsoft support specialist.

Administrator Privileges Required: You must have Global Admin or Exchange Admin privileges to perform these steps. If you are an end-user, contact your organization's IT support desk.

Frequently Asked Questions

Why did my Microsoft Bookings calendar suddenly disappear?

A calendar typically disappears if the Microsoft 365 Group associated with it was accidentally deleted, if your user account was stripped of Bookings administrator permissions, or if your Microsoft 365 business subscription expired.

Where is Microsoft Bookings data actually stored?

Bookings data is stored securely in Exchange Online. Each time a Bookings calendar is created, a dedicated scheduling mailbox is generated in Exchange to hold all the appointments, staff details, and service settings.

How long do I have to recover a deleted Bookings calendar?

If the calendar disappeared due to its Microsoft 365 Group being deleted, an administrator has exactly 30 days to restore the group from the Azure Active Directory or Microsoft 365 admin center before the data is permanently purged.

Can standard staff members recover a missing Bookings page?

No. Standard staff members or viewers do not have the administrative rights to recover deleted mailboxes or groups. You must escalate the issue to your company's IT department or Microsoft 365 global administrator.
