M365 Changelog: Bookings end point URL for customers will change

MC528980 – The self-schedule URL for the Microsoft Bookings Calendar, which is the customer facing URL for your Bookings Calendar to create/update/cancel appointments will be changed.  

Existing URL format:

“https://outlook.office365.com/owa/calendar/<Bookings_page_SMTP_Address>/bookings/” 

The new URL format:

“https://outlook.office365.com/book/<Bookings_page_SMTP_Address>/” 

Customers who have the old URL won’t face any issue as the old URL will redirect to the new URL automatically. However, if anyone has any firewall / security restriction based on the URL, they will have to add the new URL format to their allowed list to ensure the new URL won’t be blocked within or outside their org access.

When this will happen:

The changes will roll out in mid-April 2023.

How this will affect your organization:

The tenant may have to whitelist the new URL format.

What you need to do to prepare:
