FindItems operation missing from EWS since upgrade to 2013

Question

This has worked fine for years, but since ugprading to Exchange 2013 by our operations department (and possible other tweaks that I don't know about), the FindItems method is missing from EWS. I can still find it via the managed API of course (Microsoft.Exchange.WebServices.dll version 15), but calling it gives a 501 Not Implemented error. When I browse https:///ews/Services.wsdl the method is indeed nowhere to be found.

When I look at MS' documentation, I also see that the method is not there: http://msdn.microsoft.com/en-us/library/bb409286%28v=exchg.150%29.aspx . Weird, right?

What's absurd is that we have a service running i production that calls this method many times per day without logging any errors, but I cannot find the method myself. I have tried logging on to the server that the service is running on with the same user that the service runs from, and I still can't find the FindItems method in the WSDL.

Are there any other ways to "search" a user's calendar via EWS?

Answer 1

FindItems is the EWS Managed API method (http://msdn.microsoft.com/en-us/library/office/microsoft.exchange.webservices.data.exchangeservice.finditems(v=exchg.80).aspx).

FindItem (not plural, no "s") is the equivalent EWS operation (http://msdn.microsoft.com/en-us/library/aa566107(v=exchg.150).aspx). I'm seeing FindItemSoapIn and FindItemSoapOut in my Services.wsdl. If you take out the "s", can you find it then?
