Group membership isn't synced when you enable the External Identity Manager for SharePoint 2013

Applies to: Skype for Business 2015Microsoft Lync 2013

Symptoms


Assume that you set up the External Identity Provider, for example, the Forefront Identity Manager (FIM) or Microsoft Identity Manager (MIM) in Microsoft SharePoint 2013. Then you install the Forefront Identity Manager Connector for Microsoft SharePoint User Profile Store on the FIM or MIM server. In this situation, after you set up the sync, the membership changes that are queued in ImportExportStagedMember.ImportExport_PostImportMembers aren't called. The memberships also aren't synced.

Resolution


To fix this issue, install the February 7, 2017, update (KB3161988) for SharePoint 2013.
