Error when selecting Bookings from the App Store

New Contributor

Our company would like to use Microsoft Bookings.  When I click on the application from the site, I get an error message that states:


The mailbox being accessed doesn't have a valid account state (ProtocolDisabled).

Later in the error message it states:  OpenIdConnect Microsoft.Exchange.Clients.Security.AccountTerminationException


Any advice on how to overcome this?

This looks like the user account is corrupted. You would have to make a new user account under the Microsoft 365 Admin Center and assign the user as a Global GA or user account.

@firefistmango Thanks for the reply.  It appears that the root cause was that the OWA (Outlook for Web) needs to be enabled in order to use the functionality in Bookings. 

@Bruce_Kissinger Awesome! Thank you so much!
