Trouble with notifications - failed schema validation

Question

I am trying to send an Email notification from a workflow and am getting the following error:
System.Web.Services: System.Web.Services.Protocols.SoapException: The request failed schema validation: The element 'Message' in namespace 'http://schemas.microsoft.com/exchange/services/2006/types' has invalid child element 'Header' in namespace 'http://schemas.xmlsoap.org/soap/envelope/'.

It appears that the Exchange web service doesn't like the schema FIM is presenting. Anyone seen this? Is there a trace setting that will dump out the call to the Exchange
server?
I have tested that I can hit
https://fqdn_server/ews/exchange.asmx
from the FIM Service account and the certificate is correct.

Answer 1

After getting product support involved, it turns out that we were pointing the FIM Service at an Exchange 2013 server but the mailbox had been created on and was physically stored on an Exchange 2010 server. By pointing FIM at the 2010 server or by trying
to send notifications to mailboxes on the 2013 server, we could make it work. Moving the mailbox from the 2010 server to the 2013 server did not solve the problem. It had something to do with mailboxes that were originally created on a 2010 server but
were accessed over EWS from a 2013 server.
It also was not a FIM issue. We used an EWS diagnostic tool (EWSEditor) to test outside of FIM and saw the same results.
The final result to get the specific user working for notifications was to create a new mailbox for them on the Exchange 2013 server.
