Hi
We have implemented a greenfield Exchange 2013 CU1 installation for one of our customers. There are multi-role servers running Windows 2008R2, two in one data centre the third in a second running as one DAG. A number of times a day we get the following error in the Application log of each server. We're not aware of any related user issues. The error is particularly odd as it tells us to make sure there is a Exchange 2010 server in each AD site - of course being pure 2013 this cannot be the case!
Not sure if we should be worrying about this or not
regards
Nick
