Intune Connector for Active Directory – Something Went Wrong

The Problem

Installing the Intune Connector for Active Directory is a straight forward process that completes very quickly. However, after successfully installing, I was unable to Sign In.

I received the error message: Something Went Wrong. An Unanticipated error occurred. Your IT department may be able to help.

The Solution

I was using a Cloud Only global admin account that was not synced to on-premise active directory. What the documentation doesn’t tell you is that using a cloud-only account will not work. The account used for setup must be synced from the on-premise directory.

After signing in with a global admin account that is available on-premise and in cloud, the sign-in was successful.

After registration I decided to remove Global Admin permissions from the synced account used for setup and this did not seem to affect the connector at all and it’s been running fine ever since.
