Answer 1

过去，除了 Outlook 依赖性之外，安全后果使我无法使用这种方法。结果，我最终以LDAP 查询的形式构建了它。另一个优点是，（在回答您的其他问题时）您将能够提取联系信息，因为此信息存储在 Active Directory 中。

免责声明：我看这段代码已经快五年了，所以我恐怕不再完全理解这个查询。但是，希望这足以让您入门。

DirectoryEntry adFolderObject = new DirectoryEntry();
DirectorySearcher adSearcher = new DirectorySearcher(adFolderObject);

adSearcher.SearchScope = SearchScope.Subtree;
adSearcher.Filter = "(& (mailnickname=*) (| (&(objectCategory=person)(objectClass=user)(!(homeMDB=*))(!(msExchHomeServerName=*)))(&(objectCategory=person)(objectClass=user)(|(homeMDB=*)(msExchHomeServerName=*))) ))";

foreach (SearchResult adObject in adSearcher.FindAll())
{
    Console.WriteLine("CN={0}, Path={1}", adObject.Properties["CN"][0], adObject.Path);
}
