How to Manage Microsoft Bookings After the Owner Leaves
Question details
The organization needs to recover access to a Microsoft Bookings site and assign a new administrator after the original sole owner departs.
- Product
- Microsoft Bookings
- Device & OS
- not provided
- Scenario
- The sole owner of a Microsoft Bookings site has left the organization, leaving the site without an active administrator to manage bookings and notifications.
- Observed behavior
- The Bookings site becomes unmanageable because no active users have administrator access to configure settings or view appointment details.
Ensure you have the necessary administrator permissions (such as Global Administrator or Exchange administrator) to execute Exchange Online PowerShell commands. You will also need the Exchange Online PowerShell module installed on your system.
Grant Full Access Permission via Exchange Online PowerShell
Use PowerShell commands to assign full access rights to a new administrator, allowing them to manage the orphaned Bookings site.
Because Bookings sites are essentially specialized Exchange mailboxes (SchedulingMailbox), you can use Exchange Online PowerShell to grant another user access when the original owner is no longer available.
Open PowerShell as an administrator on your computer and run the connection commands to authenticate and connect to your Microsoft 365 Exchange Online environment.
Run the command 'Get-Mailbox -RecipientTypeDetails SchedulingMailbox -ResultSize:Unlimited' to output a list of all scheduling mailboxes and locate the exact identity of the orphaned Bookings mailbox.
Execute the command 'Add-MailboxPermission -Identity <BookingsMailbox> -User <BookingsSiteAdminUser> -AccessRights FullAccess -InheritanceType All'. Be sure to replace the placeholders with the actual Bookings mailbox name and the new administrator's email address.
Once the command executes successfully, have the new administrator log in to the Microsoft Bookings web app to verify access and resume managing the site.
Switch to WPS Office for Seamless and Lightweight Productivity
While managing enterprise administration tasks like Microsoft Bookings requires Microsoft 365 admin centers, handling daily documents, spreadsheets, and presentations shouldn't be complicated or expensive. WPS Office is a free, lightweight, and highly compatible alternative to Microsoft Office. It offers a familiar user interface, ensuring a seamless migration for your team without a steep learning curve.
- 1. Download the Installer: Visit the official WPS Office website and download the free installation package for your operating system.
- 2. Install WPS Office: Run the downloaded installer and follow the simple on-screen instructions to set up the software on your device.
- 3. Open Your Documents: Launch WPS Office and directly open your existing Microsoft Office files with perfect formatting preservation.
Frequently Asked Questions
Can I manage Microsoft Bookings without PowerShell?
If the sole owner has already left, a Microsoft 365 Global Administrator or Exchange Administrator must use either the Exchange admin center or PowerShell to assign a new owner to the Bookings mailbox, as standard users cannot access the orphaned site settings.
How long does it take for the new Bookings permissions to take effect?
After granting Full Access permissions via Exchange Online PowerShell, it may take up to 60 minutes for the changes to fully propagate through the Microsoft 365 environment before the new administrator can open the Bookings site.
What happens to existing appointments when the Bookings owner leaves?
Existing appointments remain intact and active within the Bookings calendar. The system continues to process customer bookings based on the existing configuration until a new administrator modifies the settings.
Can multiple administrators be assigned to a Bookings site?
Yes, you can add multiple administrators by repeating the Add-MailboxPermission command for each user, or by adding them as Staff members with Administrator roles directly from the Bookings web app once you regain access.
