Locate email on exchange server that has "/" in the name using C# and WebDAV

I asked and answered a question here that is related to this issue and sh开发者_开发技巧ows how I'm accessing my emails using C# and WebDAV. This code works fine for everything except emails that have a forward slash in the subject.

Example email subject:

"You have a new/changed record to review.eml"

Example Exchange URI:

"http://MyExchangeServerName/Exchange/MyName@Test.com/Inbox/"

The full path to this email would be:

"http://MyExchangeServerName/Exchange/MyName@Test.com/Inbox/You have a new/changed record to review.eml"

Unfortunately, this path isn't looking for the "You have a new/changed record to review.eml" email in my Inbox, it is looking for an email titled "changed record to review.eml" in the "You have a new" folder of my Inbox (which, of course, does not exist).

Is there a way to construct this string so that the forward slash of the email is recognized as being part of the true email name, rather than a subfolder of my inbox?

URL encode the subject line so that it is a valid URL. Each "/" would be replaced by its encoding "%2F".

For example, "http://MyExchangeServerName/Exchange/MyName@Test.com/Inbox/You have a new%2Fchanged record to review.eml"
