When integrating to Microsoft Dynamics CRM Online, we suddenly could not login to CRM online anymore.
We got an error message like "This is not a SOAP message."
Looks like Microsoft upgraded their CRM online login server to IIS version 8 (at least thats what they have now) and that this server responds in a slighly different way, sending one byte first and then the rest of the data. We only saw the first byte and failed to wait for the rest of the response. This is now fixed and we generally support IIS version 8 now.
If you have this problem or work with IIS version 8, please upgrade to version 3.2.90e
