FIM Azure AD Management Agent returns error Stopped-Extension-DLL-Exception on Full Import or Delta Import

AzureAD

After enabling the new Intune Mobile Device Management features inside the O365 tenant and enrolling some new devices into Intune you now have device objects in your Azure AD tenant to deal with.

The next time you do a Full Import or Delta Import you will most likely encounter a DLL Exception error in the FIM console.

If you debug the Azure connector further using the ILSpy tool and trace what line it is failing on it will most likely be this:

SchemaType schemaType = this.targetDirectorySchema.get_Types()[text];

 


Errors logged in the Application log:

FIMSynchronizationService Event 6801

The extensible extension returned an unsupported error.

The stack trace is:

“System.Collections.Generic.KeyNotFoundException: The given key was not present in the dictionary.

Updating the Schema for the Management Agent for the Azure AD tenant in the FIM Synch console and adding the missing object type (Device) to the Azure AD Management Agent resolved the issue in my case.

FIMError

 

Other scenarios known to return Stopped-Extension-DLL-Exception error in the FIM Synch console:

  • The password of your Azure AD Synch service account has expired
  • You have outdated binaries of the MSOL Sign-in Assistant installed
  • You have removed the default objects from the WAAD Synch configuration (Contact or Group when a Contact or Group is present in WAAD)
  • The Azure AD Subscription is inactive or expired
