Some users can access an unsupported early test version of the new Outlook for Windows

We are aware that some users can access an unsupported early test version of the new Outlook for Windows. This version is missing some of the features and enhancements that will be available later for our customers in the Beta Channel. We encourage our customers to wait for the beta version to be released.

We recognize the need for tenants to control access to apps in their organizations, so we are releasing early the instructions to do so. We expect to provide more news in the coming weeks about our Beta release. If you would like to block your users from connecting their Microsoft 365 accounts associated with your organization to this new app, please follow the PowerShell instructions. When the beta is available you will need to unblock them using the same instructions.

Outlook personal bookings page

Bookings in Outlook is coming to help you reduce the back and forth in scheduling, while helping you maintain control of your calendar. You’ll be able to create custom meeting types to share with others so they can easily find a time to schedule a 1:1 meeting with you according to your availability and preferences. When someone schedules a meeting with you using your personal booking page, you will both receive an email confirmation. Attendees can update or cancel scheduled meetings with you directly from your personal bookings page. Bookings in Outlook will roll out as a preview version, and you will get a new communication when it becomes GA. While Microsoft Bookings is designed for group and team scheduling, Bookings in Outlook is meant only for the owner of the mailbox and is based only on their preferences and availability.

For any entries that we are unable to migrate, they will be marked as such in the Block List and organizations will have the ability to take action as needed.

When this will happen:
