Turn off Personal Bookings

  • Article

Personal Bookings and Bookings share the same licensing model. However, Bookings doesn't have to be turned on for the organization using tenant settings for users to access Personal Bookings. The Bookings app must be enabled for users to have access to Personal Bookings.

To turn on Personal Bookings without access to Bookings, block access to Microsoft Bookings using the OWA Mailbox policy PowerShell command or follow the instructions here: Turn Microsoft Bookings on or off.

Turn Personal Bookings on or off

Personal Bookings can be turned on or off for your entire organization or specific users. When Personal Bookings is turned on, users can create a Personal Bookings page and share links with others inside or outside your organization.

Turn Personal Bookings on or off for your organization using PowerShell

You'll need to run the following commands using Exchange Online PowerShell. For more information on running Exchange Online cmdlets, see Connect to Exchange Online PowerShell. To turn Personal Bookings on or off for your organization using the PowerShell cmdlet Set-OrganizationConfig, Connect to Exchange Online PowerShell and run the following commands.

Use the Get-OrganizationConfig and Set-OrganizationConfig commands to find out the status and turn Bookings with me on or off for your organization.

Note

It usually takes about 4 hours for Set-OrganizationConfig commands to take effect for your users.

  1. Check EWS control access by running the following command.

    Get-OrganizationConfig | Format-List EwsEnabled

    If the command returns "EwsEnabled: $true" then proceed to Step 2.

    If the command returns "EwsEnabled:" (empty is default), no further changes are needed, proceed to Step 2.

    If the command returns "EwsEnabled: $false" then run the following command and proceed to Step 2.

    Set-OrganizationConfig -EwsEnabled: $true

    A. If the value of EwsApplicationAccessPolicy is EnforceAllowList, only the applications specified in EwsAllowList are allowed to access EWS and REST.

      Set-OrganizationConfig -EwsApplicationAccessPolicy EnforceAllowList -EwsAllowList @{Remove="MicrosoftOWSPersonalBookings"}
