Download the Exchange server and email address in .NET.

Question

H I. I would like to know the address of my Exchange server user (assuming that it is on a regular Windows office network). This is a C # application.

---

I already have the user's email address, I found it in System.DirectoryServices.AccountManagement.UserPrincipal.Current.EmailAddress after linking to System.DirectoryServices.AccountManagement

Answer 1

I use this for my Exchange client application.

• Install the Managed Web Services API .
• Change your C # project. Properties / Application changed the target structure to ".NET Framework 4" and not ".NET 4 Client Profile".
• Link C:\Program Files\Microsoft\Exchange\Web Services\1.1\Microsoft.Exchange.WebServices.dll

Now the code:

 var exchange = new ExchangeService(); exchange.AutodiscoverUrl(from); var server = exchange.Url.Host; Console.WriteLine(server); 

Here is the MSDN documentation . but pay attention to the unreleased version 1.2 of the API. I can not find documentation for version 1.1

Answer 2

You are looking for an AD attribute called homeMDB: http://msdn.microsoft.com/en-us/library/ms980583(v=exchg.65).aspx

I don’t think there is a good .NET wrapper for this attribute, so to get it you need a lower level LDAP API.

Note that with later versions of Exchange (such as 2010), you can connect to any CAS role, and Exchange will determine the routing.

Have you studied using autodiscover? http://technet.microsoft.com/en-us/library/bb124251.aspx
