I’m adding another entry to my series of posts on User Profile Service Application errors in SharePoint 2010. This particular error occurs after you pick the Active Directory OUs you want when creating a synchronization connection. Specifically when trying to save the new connection, you might receive the following error.
Unable to process Create message
There are a variety of causes to it, but I wanted to share my specific resolution today. I received this error after I went from December 2010 CU to February 2011 CU. Although, upgrading to the latest CU resolved my error from earlier, it presented the new one I mentioned above. When I applied the February CU, surprisingly, the User Profile Service did not require reprovisioning. However, every time I tried to save my synchronization connection, I received the error. Finally, to resolve the issue, I deleted the User Profile Service application and recreated it. Once I did that, I restarted UPS and was able to create the connection.
