storing email signature on MS Exchange Server via MAPI using C#?

is there 开发者_Python百科a way to programatically store email signatures on MS Exchange Server via MAPI using C#?

Email signatures are only stored and applied on the client, not on the server. They are also not exposed by MAPI on the client. I have heard of some applications that can help you manage email signatures across your client machines, but I have never used any.
