Avery weird issue just started happening. I'm trying to create mail enabled security groups in FIM 2010 R2 (v4.1.3613.0), and when I go to modify the number to flow into GrouptType nothing happens - no error messages - nothing logged in the event viewer.
I tried rebooting the SQL Server and then once that was back, I tried rebooting the FIM Server.
I tried creating a new Sync rule and when I get to the Outbound Attribute Flow tab I enter the required values in the New Attribute Flow button, but nothing ever get populated in the tab.
