One of the most looked at topics on this blogpost is the ImmutableID series for Azure AD Connect and AADSync. And I wanted to give an update to this, given the latest versions of Azure AD Connect seemed to have adopted the idea to use the ms-ds-ConsistencyGuid (or any other value) to replace the ImmutableID used for synchronization. Don’t worry, please keep reading the other posts, as they clearly explain the how behind the idea of using the alternative ImmutableID.. and this post is just to tell you.. Microsoft has made the implementation a lot easier!
