    Get all mailbox information from WMI & C#.Net

    • 0 Comments

    In one scenario, there was a need for me to get all mailbox related information using WMI and C#.Net.

    Here is a code snippet to get all mailbox information from an Exchange Server - WMI & C#.Net.

    using System;
    using System.Management;

    namespace ConsoleTwo
    {
        class Class1
        {


            [STAThread]
            static void Main(string[] args)
            {
                try
                {
     
                    System.Management.ConnectionOptions objcon = new System.Management.ConnectionOptions();
                     objcon.Impersonation = ImpersonationLevel.Impersonate;
     
                    // Exchange Server Name
                    string cServername = "Server Name";
     
                    // Create a management scope into Exchange WMI namespace
                    System.Management.ManagementScope exScope =
                        new System.Management.ManagementScope(@"\\" + cServername + @"\root\MicrosoftExchangeV2", objcon);

                    // Create a query to get the data from the Exchange WMI
                    System.Management.ObjectQuery objQry =
                        new System.Management.ObjectQuery("SELECT * FROM Exchange_Mailbox");

                    // Retrieves a collection of management objects based on the query.
                    System.Management.ManagementObjectSearcher objSrch =
                        new System.Management.ManagementObjectSearcher(exScope, objQry);
                    System.Management.ManagementObjectCollection qryCol = objSrch.Get();

                     // Loop each item in the collection
                    foreach (System.Management.ManagementObject mailBox in qryCol)
                    {
                         Console.WriteLine("{0} {1} {2}", mailBox["MailboxDisplayName"].ToString() , mailBox["TotalItems"].ToString() , mailBox["size"].ToString() );
                     }
                 }
                catch (Exception eVal)
                {
                    Console.Write(eVal.InnerException + eVal.Message + eVal.Source + eVal.StackTrace );
                }
                Console.Read(); 
            }
        }
        }

    Event sink: Will it sink?

    • 0 Comments

    Lets we discuss about Event sink: It will sink?

    Just for words, it might be fascinating or it will be funny to hear such remarks. Some guys even crib about that too; but it's not actually. Event sink is one of the strongest feature available in Exchange environment; they're helpful in many scenarios and quite lot of applications wrapped around it.

    I have worked with couple of scenarios with Event sink; it can be used to monitor the incoming/outgoing mails, virus scanning applications, stripping attachments, spam filters etc.

    So what is a Event sink

    It's a piece of code which defines how the server or the computer is to handle the given events.

    What it can be used for?

    They can be used as spam filters to fire certain actions;

      • act as spam filter
      • to find certain types of attachments
      • can get response to the receipt of an e-mail message with certain characteristics
      • to strip out the incoming/outgoing attachments
      • download the attachments to specific physical folders
      • block the attachments within their org/enterprise level
      • to delete excessive data sent............................................. for more information, please click here

    What are the Technologies can we create event sinks:

    • VB Script
    • Managed Sink - Created & compiled in .Net framework
    • C++

    Types of Event sinks:

    • Synchronous
    • Asynchronous
    • System
