Applies to Product - Dynamics 365 Business Central

What’s happening?
Users who have left the company and returned are unable to reconnect their Business Central (BC) accounts with their Entra ID after the Entra ID was deleted and subsequently recovered. When attempting to sync users, a new account is created that is not functional.
 

Reason:
This arises when a user account is deleted and then recovered, leading to complications in reconnecting the existing BC account with the Entra ID.
 

Resolution:

  1. Ensure the user's email in Microsoft 365 (Azure AD) is correct.
  2. In Business Central, navigate to the Users section.
  3. Select the "Update Users from Microsoft 365" action. This action will synchronize the user information from Microsoft 365, including the authentication email, with Business Central.
  4. If the synchronization does not resolve the issue, verify that the user has been assigned a Business Central license in the Microsoft 365 admin center.
  5. Have the user sign out of all Microsoft services and then sign back in using their Entra ID (formerly Azure AD) credentials.
Note: The "Update Users from Microsoft 365" guide does not update users that are not assigned a license, such as Global Admins and Dynamics 365 Admins. Those users will update the next time they sign in to the environment.
