How to block Microsoft Bookings Access in Tenant


In this article, you will learn how to block Microsoft Bookings Access in Tenant.

Microsoft Bookings, An appointment platform recently introduced by Microsoft for enterprise customers globally. As tenant Admins, we should know how to manage Microsoft Bookings access for users in the tenant and provide required access to specific users while blocking it for the rest.

block Microsoft Bookings Access in Tenant

Before getting into the details, Those who already implemented MS Bookings at the initial phase are aware that “Business Apps” with Bookings add-on was required and we need to purchase free licenses in the “Business Apps” service to assign the Microsoft Bookings license to the users.

While it might sound confusing, people who are associated with Microsoft from a while now will understand this. Microsoft generally launches the apps and services through an add-on for testing and implementation, needless to mention, checking the demand of the product as well. Which later gets integrated as a part of licensing service. Below is a notification from Microsoft that we received in around mid of March 2020.

Important: These steps only apply to Microsoft 365 subscriptions that are purchased directly by customers. Beginning mid-May, 2020, the add-on process will be removed and Bookings will be available as on by default to Office 365 Enterprise E3 and Office 365 Enterprise E5 customers. Once that change occurs, follow the instructions in the “Access Microsoft Bookings” and “Turn On/Off Access to Microsoft Bookings” section of this page.


With the huge success and demand of Microsoft Bookings, it’s now directly added to various licenses (Enterprise Exchange, E3, E5, etc.) as an app/service.

We no longer need the “Business App” to assign a Bookings license. Below is the snapshot from my test tenant for one of the users to show how it should look now-

Go to the path: Microsoft Admin Center>Active Users>Select User>Licenses and Apps>Apps

Now coming back to restricting the access of MS Bookings for users in the tenant, we will quickly understand, as Admin, why you wish to do this and the steps to implement –

Why do we need to Block Microsoft Bookings Access?

With Microsoft Bookings License, the users will not only have the capability to access other Microsoft Bookings Calendar but also create new Microsoft Bookings Calendar of their own.

Please note that Microsoft Bookings Calendar is generally created for an entire business to align available resources towards the customer requirement. As an Admin, we should prevent every user from creating the Microsoft Bookings Calendar.

We already understood the importance of preventing users from creating the Microsoft Bookings calendar, let’s discuss how it can be implemented on a tenant level.

Below are two possible ways to do that :

Method 1: Customizing Licensing

  1. Implementing a Group-based licensing option in Azure for new users to disable Microsoft Bookings App (Azure)
  2. Assigning the Custom licenses to the users in tenant by creating a licensing option with disabled Microsoft Bookings App (Only be implemented in Powershell scripting – Please refer to my other blog on how to implement the custom licensing or MS article “Disable access to Microsoft 365 services with PowerShell”

Method 2: Using OWA mailbox policy

I will discuss the second method with the implementation of the changes in the OWA mailbox policy. In this method, we Disable the Microsoft Bookings Mailbox Creation in the OWA Mailbox policy and applying that to respective users.

Below are the steps to implement this with Powershell

1. Connect to Exchange Online Powershell


 2. Create a new OWA mailbox policy

New-OwaMailboxPolicy -Name DisableBookingsMailboxCreation

3. Disable Bookings Mailbox Creation for this OWA mailbox policy

Set-OwaMailboxPolicy -Identity DisableBookingsMailboxCreation      -BookingsMailboxCreationEnabled $false

4. Please verify the changes made in the policy

Get-OwaMailboxPolicy -Identity DisableBookingsMailboxCreation | Select BookingsMailboxCreationEnabled

5. Assign this policy to the users that you want to prevent from creating a new Bookings Calendar in the tenant. We can assign the policy through Powershell as well as GUI.

I have implemented this of one test user in my tenant, below is how the expected behavior should be –

Set-CASMailbox -Identity -OwaMailboxPolicy "DisableBookingsMailboxCreation"

6. User should get below error –

“You do not have access to create a new Booking Calendar. Contact your administrator to enable access”

Below is the view from my powershell for the entire implementation –

I hope this helps!

Targeting the Tenant Admins and specific to MS Bookings, I have not included more details on scripting and bulk user implementation. Please refer to my other post on Creating and Assigning Custom licensing Options in Microsoft Office 365

  1. Thank you so much AMOL! This article has helped our organisation a great deal to stop the wild growth of Booking pages!

  2. Thank you so much for this article! If we wanted to implement Bookings to all our A3 licences users (14,000+), but block the ability for them to create booking calendars themselves and restrict the creation to a very small subset of users – how would you best approach this?
