Help on MailItems and AD addressesIn C#/.NET 2.0: How can I reply to an Email address retrieved from an
Exchange server MailItem? I am using Interop Outlook.MAPIFolder to retrieve Outlook.MailItem's. I want to send an automated response to the sender of each MailItem, but MailItem.SenderEmailAddress is something like "/O=COMPANY/OU=ADMIN GROUP/CN=RECIPIENTS/CN=USERNAME". I don't know what that is, though I assume it has something to do with active directory. I can send messages using SMTP addresses in my current environment. Is there a straightforward way to retrieve the SMTP address for an Exchange user in a situation like this? MailItem also exposes a tempting public method "Reply()", which produces another MailItem object with a method "Send()", but when I call it I get an exception trying to cast the Reply to a MailItem. Can anyone offer a working example of how to reply using MailItems? This is a normal EX type address. How exactly are you sending messages? If
you have the EX provider in your current profile, using an EX address should not pose any problems. If you are using Outlook 2007, you can use ExchangeUser.PrimarySmtpAddress property.

Can you point me to docs or exampels? Also can you point me to documentation on the construction and validation of EX addresses?

the Exchange provider - anything based on Extended MAPI (that includes Outlook Object Model and CDO 1.21) will let you do that. If you are retrieving the address through OOM, why not use OOM to send the message? If you absolutely need to send through SMTP, you can retrieve the SMTP proxy addresses using Extended MAPI (C++/Dephi only), CDO 1.21 or <plug> Redemption (which also exposes the AddressEntry.SmtpAddress for all address entries on all version of Outlook) </plug>: essentially you will need to retrieve PR_EMS_AB_PROXY_ADDRESSES multivalued property with all proxy addresses for for the given EX address entry.

address 90% of the battle is over. That's AD-speak for who the recipient is. If you want to send to that address via System.Net.Mail, you can query AD for the actual email address and use that: make sure you include System.DirectoryServices; (requires a .NET added reference) DirectoryEntry de = new DirectoryEntry("LDAP://[domain.com]/[O=COMPANY/OU=ADMIN GROUP/CN=RECIPIENTS/CN=USERNAME]", @"[domain\username]", "[password]"); [in the above, replace bracketed parts with your domain information/credentials] Then, there is probably a better way to get the email from here, but this is a way that's worked for me: DirectorySearcher ds = new DirectorySearcher(); ds.SearchRoot = de; ds.Filter = "(SAMAccountName=*)"; //query for all aliases (SAMAccountName) matching this "AD address" ds.SearchScope = SearchScope.SubTree; //simplistic results w/o error checking SearchResult sr = ds.FindOne(); string alias= sr.Properties["SAMAccountName"][0]; //need to handle nulls/0 results/multiple results here you can youse Properties["mail"] if you want the full email address and not just the alias for alias@[domain.com]. Then you can send to it like normal If you need more help you can try the System.DirectoryServices documentation. Make sure your LDAP is in upper case.

actually, the address you get here is an Exchange legacy distinguished name, used by Exchangg 5.5. Since Active Directory uses normal distinguished names, you can not use the legacyExchangeDN to bind to the object. You must perform an LDAP search to get the object: DirectoryEntry entry = new DirectoryEntry("dc", "username", "password", AuthenticationTypes.Secure); DirectorySearcher searcher = new DirectorySearcher(entry, "(legacyExchangeDN=/O=COMPANY/OU=ADMIN GROUP/CN=RECIPIENTS/CN=USERNAME)"); SearchResult sr = searcher.FindOne(); if (sr == null) { // User not found } else { // User found } Substitute the "dc" with something like this: LDAP://[domain.com]/DC=Domain, DC=com. If your Active Directory spans more than one domain, you're probably better of using GC://[domain.com]/DC=Domain, DC=com, where "DC=Domain, DC=COM" should be the distinguished name of the Root domain. This will perform a search on a Global Catalog server, which contains information about all objects in a forest. Note that you can omit the [domain.com] completely, if the computer you are using is in the domain.
