Here’s an issue I ran into the other day that I thought you might be interested in hearing about. It’s probably not something that will be very common but I wanted to pass it along anyway just in case.
The basic issue is that you find you’re unable to create an Exchange connector (Exchange Connector 3.0 RTM). When you try to create the connector, after you provide the RunAs account and click on Test Connection you see the error below:
impersonation=: Message=Unable to validate credentials, please refer to the event logs for more information (Error Type=MissingMethodException, Message=Method not found: 'Microsoft.Exchange.WebServices.Data.FindItemsResults`1<Microsoft.Exchange.WebServices.Data.Item> Microsoft.Exchange.WebServices.Data.ExchangeService.FindItems(Microsoft.Exchange.WebServices.Data.WellKnownFolderName, Microsoft.Exchange.WebServices.Data.SearchFilter, Microsoft.Exchange.WebServices.Data.ItemView)'.)
Based on the error, it seems that the ''Microsoft.Exchange.WebServices.Data.FindItemsResults' method is missing from Microsoft.Exchange.WebServices.dll (which comes from the Service Manager 2012 SP1 installation media).
The Microsoft.Exchange.WebServices.dll file version has to be 18.104.22.168 as this dll has the method that is required for configuring the Exchange connector.
So what we did was install a copy of the file by downloading and installing Exchange Web Services Managed API 1.2 from the following location:
Once we replaced the Microsoft.Exchange.WebServices.dll file in the SCSM installation folder with the one installed by Exchange Web Services Managed API 1.2 the issue was resolved.

Is it possible to use EWS Managed API 1.2.1 (looks like this has the required method)?
