I have noticed an error that keeps coming up in the event log of my HUB/CAS/MBX server:

WebHost failed to process a request.
 Sender Information: System.ServiceModel.ServiceHostingEnvironment+HostingManager/30542218
 Exception: System.ServiceModel.ServiceActivationException: The service '/EWS/Exchange.asmx' cannot be activated due to an exception during compilation.  The exception message is: A binding instance has already been associated to listen URI 'http://server.domain.com/EWS/Exchange.asmx'. If two endpoints want to share the same ListenUri, they must also share the same binding object instance. The two conflicting endpoints were either specified in AddServiceEndpoint() calls, in a config file, or a combination of AddServiceEndpoint() and config. . ---> System.InvalidOperationException: A binding instance has already been associated to listen URI 'http://server.domain.com/EWS/Exchange.asmx'.

This error does not go away, any help is appreciated.

Thanks,

Are you having issue with deleting emails in OWA? If so, there is a lie issue in the TechNet Exchange forums (http://social.technet.microsoft.com/Forums/en/exchange2010/thread/ae23796c-7853-47e1-a8ed-3b7d6be04b7f) that you may want to watch.

I should have mentioned that I have SP1 installed so the first link doesn't seem to have any changes appropriate to me.  It also said that SP1 enables the behavior of 2007.

I am not having any issues deleting out of OWA.

Any other thoughts?
