与EXCHANGE有关 會的絕對是高人
麻煩解釋一個   以下添加郵件帳號和NT帳號的含義
ExchangeAcctLib.AcctMgmt   objAcct   =   new   MSExchangeAcctLib.AcctMgmtClass();
                                               
object   obSID;
object   obSD;
string   strDCT   =   "2A864886F7140501 ";

objAcct.GetSidFromName(strDomain,strUsername,out   obSID);
objMailbox.Properties[ "Assoc-NT-Account "].Add(obVal);
objAcct.GenerateSecDescriptor(strDomain,strUsername,   out   obSD);
objMailbox.Properties[ "NT-Security-Descriptor "].Add(obSD);
objMailbox.Properties[ "Deliv-Ext-Cont-Types "].Add(strDCT);
objMailbox.CommitChanges();
objMailbox.Close();
