I am trying to get OAuth and EWS working for sending emails.
The problem is that I get a message about SOAP and impersonation when I create the EWSClient. ( ExchangeImpersonation SOAP header must be present for this type of OAuth token)
EWSClient has an ImpersonateUser function, but I do not get to the point that I would be able to use it. It looks like the token I am getting is correct.
var tokenProvider = new MsTokenProvider(oAuth, server.Address); var credentials = new OAuthNetworkCredential("firstname.lastname@example.org", tokenProvider); asposeClient = EWSClient.GetEWSClient(url, credentials);
Any hints on getting impersonation working when using OAuth?
