ExpandDL - "Try again later" error even after successful ResolveNa
First, I love all the new web services so thanks a lot for those.
My problem is in getting the ExpandDL to work. I got a vague error message
when running even a simple example (like from the documentation). Here is
the error message I receive:
Active Directory operation did not succeed. Try again later.
Just to make sure I was connecting properly and such, I tried doing a
ResolveNames on the alias first. Then, I set the Mailbox on the ExpandDL
request to the one I got returned from the ResolveNames with the very same
ExchangeServiceBinding instance, and I still got the exact same error.
Is this a known issue, or is there something obvious I could be doing wrong?
That's my main question, and I'm not asking for someone to go through this,
but if anyone is interested here's the C#:
ExchangeServiceBinding esb = new ExchangeServiceBinding();
esb.Url = "[edited out]";
esb.Timeout = 300000000;
esb.Credentials = new NetworkCredential([edited out]);
ResolveNamesType rnt = new ResolveNamesType();
rnt.ReturnFullContactData = true;
rnt.UnresolvedEntry = [edited out];
ResolveNamesResponseType rnrmt = esb.ResolveNames(rnt);
Console.WriteLine(rnrmt.ToString());
ResponseMessageType[] types = rnrmt.ResponseMessages.Items;
if (types == null)
{
Console.WriteLine("Error! null returned");
}
else if (types.Length < 1)
{
Console.WriteLine("0 results returned");
}
else
{
ResponseMessageType type = types[0];
if (types.Length > 1)
{
Console.WriteLine("More than 1 (" + types.Length + ")
record returned, taking first");
}
Console.WriteLine("Success! " + type.ToString());
ResolveNamesResponseMessageType type2 = type as
ResolveNamesResponseMessageType;
if (type2.ResolutionSet.Resolution.Length < 1)
{
Console.WriteLine("No resolved names");
}
else
{
ContactItemType contact =
type2.ResolutionSet.Resolution[0].Contact;
if(type2.ResolutionSet.Resolution.Length > 1)
Console.WriteLine("More than 1 (" +
type2.ResolutionSet.Resolution.Length + ") resolved name returned");
Console.WriteLine("Display Name: " + contact.DisplayName);
if(contact.EmailAddresses.Length < 1)
Console.WriteLine("No email addresses listed");
else
Console.WriteLine("Email Addresses:");
for(int i = 0; i < contact.EmailAddresses.Length; i++)
Console.WriteLine(contact.EmailAddresses[i].Key.ToString() + ": " +
contact.EmailAddresses[i].Value.ToString());
Console.WriteLine("\r\n\r\nLooking into each address for
expandedDL:");
for (int i = 0; i < contact.EmailAddresses.Length; i++)
{
LookupEmail(esb,
type2.ResolutionSet.Resolution[0].Mailbox);
}
}
}
[separate function:]
private static void LookupEmail(ExchangeServiceBinding esb,
EmailAddressType eat)
{
Console.WriteLine("Looking up " + eat.ToString());
ExpandDLType expandDl = new ExpandDLType();
expandDl.Mailbox = eat;
//expandDl.Mailbox.EmailAddress = email;
// Expand the dl
ExpandDLResponseType expandDlResponse = esb.ExpandDL(expandDl);
// Check the result
if (expandDlResponse.ResponseMessages.Items.Length > 0 &&
expandDlResponse.ResponseMessages.Items[0].ResponseClass ==
ResponseClassType.Success)
{
ExpandDLResponseMessageType dlResponse =
expandDlResponse.ResponseMessages.Items[0] as ExpandDLResponseMessageType;
// Get the dl expansion list
ArrayOfDLExpansionType expansionList = dlResponse.DLExpansion;
// Display the dl members
foreach (EmailAddressType address in expansionList.Mailbox)
{
Console.WriteLine("Email Address: {0}",
address.EmailAddress);
}
}
else if (expandDlResponse.ResponseMessages.Items.Length > 0)
{
Console.WriteLine("Error: " +
expandDlResponse.ResponseMessages.Items[0].MessageText);
}
else
Console.WriteLine("No results returned");
}

RE: ExpandDL - "Try again later" error even after successful ResolveNa
I couldn't figure this out, so I learned about this LDAP/DirectoryEntry
ActiveDirectory stuff and it appears to be working great and fast. I have a
feeling the "web service" route is more current and will likely be around
longer, so if anyone knows the answer to my previous problem please feel free
to reply and I'd appreciate it.
I initially was trying this because there's limited MAPI support in C# and
iterating through the whole address book would have taken days. In case
anyone else has this problem, I personally found the ActiveDirectory
documentation difficult to navigate so here's a quick example ([] = edited
out):
DirectoryEntry de = new
DirectoryEntry("LDAP://a.b.com/OU=Distribution Lists,DC=a,DC=b,DC=com",
@"[domain\username]", "[password]");
DirectorySearcher ds = new DirectorySearcher();
ds.SearchRoot = de;
ds.Filter = "(SAMAccountName=[DL alias (e.g. the DL c@b.com
would be just c)])";
ds.SearchScope = SearchScope.Subtree;
//this next part could use more robustness in case there's multiple results,
errors, etc.
SearchResult results = ds.FindOne();
if (results.Properties["member"] != null)
{
foreach (string s in results.Properties["member"])
Console.WriteLine("Member: " + s);
}
The connection string is the hardest to figure out. And the "LDAP" has to
be upper case or else. Here it is again:
"LDAP://a.b.com/OU=Distribution Lists,DC=a,DC=b,DC=com"
--a.b.com should be self-explanatory
--Distribution Lists: this might not be the same for you, that's just what
the DL list was called in the tree I was using. You can open the connection
without this part of the connection string (e.g.
"LDAP://a.b.com/DC=a,DC=b,DC=com") and do the same sort of search with the
search string "(OU=*)", the results of property "ou" instead of "member" will
give you all the "organizational units" to look through to find the DL one
--If you have a different subdomain structure, just keep adding or removing
"DC=X," until you spell it all out (e.g. "DC=a,DC=b,DC=c,DC=com" for
a.b.c.com)
--When you get these results back you will see they are in this same crazy
format, like "CN=[Name],OU=[something like "Accounts"],DC=a,DC=b,DC=com". If
you need the alias, you can make a new DirectoryEntry with this string and
get the "mail" property for the email address. Also if someone is on a DL
which is on a DL and you're searching the top one, you will need to recurse
through; instead of just checking for the email of each result check if you
need to expand it to a DL (property OU="Distribution Lists" or the equivalent
in your tree) and then reconnect there and search for subDLs.
--also if you want the groups a specific user is in, make one of the search
strings for that user (try search filter "(SAMAccountName=[alias])"), then
look up the all the groups they're in using the "memberof" property.
Hopefully this helps someone else having the same problem, but if not oh
well. :)
This isn't formal or ideal or anything, so there's probably much better ways
to do all this (and this ActiveDirectory stuff appears to often have many
ways to query the same thing).
