Azure AD connect, view disconnectors

What is a disconnector?

A staging object that is not linked to a metaverse object is called a disjoined object (or disconnector object). In other words, some attributes from your on-premises Active Directory are not correctly synchronized with Azure Active Directory.

Options to check\view disconnectors?

With Azure AD connect there are no options to view these disconnectors. The feature was present with DirSync but now is decommissioned in Azure AD Connect. The main reason is that these disconnectors are not affecting your synchronization process.

Options to fix disconnectors issues?

These disconnectors issues are coming only from your on-premises AD and then populated to Azure AD. The starting point is to verify and cleanup your on-premises AD before having your first synchronisation with Azure AD. You can use IdFix tool, additional information in the following article: https://support.office.com/en-us/article/Install-and-run-the-Office-365-IdFix-tool-f4bd2439-3e41-4169-99f6-3fabdfa326ac

If you have already synchronized your AD with Azure AD (before cleaning it up) the only way to fix these disconnectors is:

  1. Verify and clean up your on-premises AD using IdFix tool
  2. Perform a clean Azure Active Directory  installation (re-create the mysql metaverse database) using the following steps:
