It’s in the Exchange Server Examples region. Yeah, you are right the document didn’t mention this method. I was just going through some samples and hit this problem. Being a bit rusty with C# it took me a while to figured it out: the WebDav folder was not using in RunExamples.
Thanks for your explanation about WebDav…I did have wondered what’s the difference between EWS and WebDav. Now I guess that the WebDav folder probably not being referenced to on purpose, but because the samples are mixed together in the Exchange Server Examples region, it’s a bit confusing. It would be nice if all the WebDav samples could be separated and have its own region.
Again, thanks for your prompt response!
