check your account settings and permissions, primarily Impersonation settings if you are using impersonation. one of those is usually the cause of this problem.

Agree with above, most likely cause is impersonation.

Hi Thomas,

Thanks for your attention, but Im not using impersonation, my account has a mailbox, also I tryed to configure using impersonation and Im getting the same error, for me looks like something with Exchange server I will try to forward the error to the Exchange team to see if they can give me a light....

try connecting directly to the web service as a test. Also enable additional logging to help see what the issue is. The additional logging helps a lot

Hi Guys,

Just to let you know we found the problem, was the exchange forms, we need to disable the forms on OWA, then worked fine.

OWA shouldn't have anything to do with Exchange Web Services. perhaps there was a separate permissions issue?

Just use the RUN AS account in this form   Domain\Account  or   account@domain.com

this worked with me fine
