Re: Help on MailItems and AD addresses
If you are sending to an EX address, you obviously need to do that through
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.

RE: Help on MailItems and AD addresses
Once you have this "/O=COMPANY/OU=ADMIN GROUP/CN=RECIPIENTS/CN=USERNAME"
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.

Re: Help on MailItems and AD addresses
Hello,
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.
Best regards,
Henning Krause
