M365 Changelog: Microsoft Bookings – Custom domain support

MC485090 – You can now specify which domain will be used from the domain list for Bookings using OWA mailbox policy. Once default domain policy is configured and deployed, any new booking calendars created will have the configured domain in the SMTP address.

For example: Booking pages can get created with a domain “contoso.com” instead of “contoso.onmicrosoft.com”.

You are also allowed to Configure domain for specific users. When users with the custom OWA policy create a Booking calendar, it would get created with the custom domain and not the default domain

When this will happen:

Custom domain support is now available to all tenants worldwide.

How this will affect your organization:

Your admin will now have the option to add custom domains and define domain to be used for Bookings calendars. They can now also configure a domain for specific users.

This change will not impact Bookings calendars that have already been created. Only new calendars will be created using the configured domain.

What you need to do to prepare:

This is a great new feature which can benefit your organization. You may wish to inform your users to utilize this feature and share the documentation Custom domain support in Bookings
