CDOEXM & C#.Net : How to mail-disable public folders in Exchange Server 2003 SP2 – Native Mode?

I created this code snippet, which helps us to mail-disable in the Exchange Server 2003 SP2 (Native mode) – public folders. For this i tried this, i used C#.Net & CDOEXM. In this below code, i try to mail-disable the public folder named “publicfolder1”. I used Visual Studio.Net 2008, C#.Net and CDOEXM – Collaboration Data Objects for Exchange Management – 2003 to do this:

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using CDO;

using CDOEXM;

using System.Collections; 

namespace MailDisableCSharp

{

    class Program

    {

        static void Main(string[] args)

        { 

            try

            {

                CDO.Folder objFolder = new CDO.Folder();

                CDOEXM.IMailRecipient objRecip;

                string fullurl;

                fullurl = "http://domain/public/publicfolder1";

                objFolder.DataSource.Open(

                                fullurl,

                                null,

                                ADODB.ConnectModeEnum.adModeReadWrite,

                                ADODB.RecordCreateOptionsEnum.adFailIfNotExists,

                                ADODB.RecordOpenOptionsEnum.adOpenExecuteCommand,

                                "Administrator",

                                "Password"); 

                objRecip = (CDOEXM.IMailRecipient)objFolder;

                objRecip.MailDisable();

                objFolder.DataSource.Save();

                Console.Write("Success");

             }

            catch (Exception e1)

            {

                Console.WriteLine(e1.Message);

           } 

        }

    }

}

Note:

+ To execute this code, you may try with VS.Net 2005 or VS.Net 2008, C#.Net.
+ Make sure you need to use the following references: CDOEXM – Microsoft CDO for Exchange Management 2000 & CDOEX - Microsoft CDO for Exchange 2000.
+ This code helps us to mail-disable the public folder “public folder1”.
+ Also we need to make sure to pass valid credentials username(Administrator) & password(Password) to execute this, along with valid fullURL – the public folder needs to be mail-disabled & domain – exchange domain.

Hope this helps. Happy programming!!

General : Do you know what is “ReadyBoost” technology ?

ReadyBoost technology takes advantage of the fact that flash memory offers lower seek times than hard disks. Essentially that means that your system can get to a given location on a flash disk more quickly than it can to a corresponding spot on a hard disk. Hard disks are faster for large sequential reads; flash disks are quicker for small, random reads. When a supported external memory device is available, ReadyBoost caches small chunks in flash memory and is thus able to retrieve those chunks, when needed, more quickly than it could if it relied only on the hard disk.

Because an external memory device can be removed without warning to the system, all data cached via ReadyBoost is encrypted and backed up on the hard disk (as well as being compressed). Encryption ensures that the data can’t be read on another system, and backup enables Windows to revert to the hard disk cache in the event that the ReadyBoost drive is removed.

Windows supports the following form factors for ReadyBoost:

•USB 2.0 flash disks

•Secure Digital (SD) cards

•CompactFlash cards

When you connect a device of one of these types to your system, Windows runs a quick performance test to see if the device meets minimum standards required for ReadyBoost. Those standards are:

•2.5 MB / second throughout for 4 KB random reads

•1.75 MB / second throughout for 512 KB random writes

In addition, the device must have at least 256 MB available for the ReadyBoost cache.

Note: ReadyBoost does not support external card readers. If Windows Explorer shows a volume letter for a drive without media (as it does, for example, for card-reader drives or floppy drives), inserting flash media for that volume letter will not give you a ReadyBoost drive. In addition, Windows Vista does not support multiple ReadyBoost drives. (Microsoft has indicated that multiple-drive support is under consideration for future versions.)

How much boost will you get from ReadyBoost?
As with so many other performance issues, it depends. If your internal memory is well above the amount you actually need, ReadyBoost won’t do much for you. If not, you should definitely see some performance improvement. To use ReadyBoost, follow these steps:

1. Plug a suitable external memory device into your computer. An AutoPlay window similar to the following will appear (it won’t say READYBOOST, unless you’ve already assigned that name to the volume, as we have here):

This window appears when you plug a ReadyBoost-compatible memory device into your computer

2. Click Speed up my system. If your system passes an initial ReadyBoost test, the Properties dialog box will appear, with the ReadyBoost tab selected:

Use the slider to set aside space on your memory device for ReadyBoost

•Select Use this device, and then adjust the slider to specify the amount of space you want to use for ReadyBoost. Then click OK.

How much of the external memory device you want to assign to ReadyBoost will depend on whether you also want to use the device for ordinary storage. Microsoft estimates that you can benefit from a ReadyBoost cache equal to approximately 150 percent of your system RAM—for example, a 1.5 GB ReadyBoost cache on a 1 GB systems.

Windows Mobile : Windows Mobile 6.5 Developer Tool Kit available

If you’re a Windows Mobile developer, then this is for you.

While this has been a much-awaited release for the developer community, some confusion has arisen in the media. To clarify, the Windows Mobile 6.5 Developer Tool Kit (DTK) is not an SDK. The DTK contains emulators, gesture APIs, and samples useful for developing Windows Mobile 6.5 applications (both Standard & Professional Emulators available). Developers will still need to install Visual Studio and the Windows Mobile 6 SDK prior to running the tool kit installer.

The Windows Mobile 6.5 Developer Tool Kit adds documentation, sample code, header and library files, emulator images and tools to Visual Studio that let you build applications for Windows Mobile 6.5. This document contains important information about this package. The Windows Mobile 6 SDK must also be installed in order to use any of the Windows Mobile 6.5 Gesture API or samples. Windows Mobile 6.5 Developer Tool Kit comes with the following Emulator Images:

• Windows Mobile 6.5 Professional Square Emulator
• Windows Mobile 6.5 Professional QVGA Emulator
• Windows Mobile 6.5 Professional WQVGA Emulator
• Windows Mobile 6.5 Professional VGA Emulator
• Windows Mobile 6.5 Professional WVGA Emulator
• Windows Mobile 6.5 Standard Square Emulator
• Windows Mobile 6.5 Standard QVGA Emulator

Available locales:
0804 CHS Chinese Simplified
0409 USA English
0407 GER German
040c FRA French
0410 ITA Italian
0c0a ESN Spanish

A new set of APIs is being introduced that will enable application developers to take advantage of the new Windows Mobile 6.5 touch gesture framework. The gesture APIs allow an application to handle touch gesture input and provide a visually consistent experience with the rest of the device UI. Note that the gesture APIs are only available on the Windows Mobile Classic and Professional SKUs. The headers and libraries are installed in the Windows Mobile SDK\Pocket PC\ folder. Samples that make use of these APIs are installed into the Windows Mobile 6.5 Developer Tool Kit\Samples\ folder.

.Net Troubleshooting : How to uninstall the components of the .NET Framework 3.5 SP1?

Do you want to un-install the components of the .Net Framework 3.5 SP1?

Then you need to read this article (article by Aaron),  in which he described his experience, how to uninstall the components of the .Net Framework 3.5 SP1?

He gave the clear step-by-step information how we can uninstall the components of the .Net framework 3.5 SP1 in Windows XP, Windows Server 2003, Windows Vista and Windows Server 2008.

Troubleshooting : EWS request throws “The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel” ?

One of my customer updated that whenever they try to make the remote Exchange Web Service (EWS) call from his C#.Net 2008 application (VS.Net 2008 - .Net Framework 3.x), he gets the following error:

The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel

I had a detailed look at their application code.

// Create the Exchange Service Binding        

ExchangeServiceBinding esb = new ExchangeServiceBinding();        

// Add its relevant Credentials like user name, password, domain and URL        

esb.Credentials = new NetworkCredential(userName, Password, domain);        

esb.Url = @"https://myexchangeserver/EWS/Exchange.asmx";

We checked the credentials passed; it seems everything was fine. But still it was failing whenever we make the request to the server with the above same message. When we checked their environment, we found customer uses the self-signed certificate on the server. This is because, by default, .NET checks whether SSL certificates are signed by a certificate from the Trusted Root Certificate store.

To over-ride this behavior, we need to use the following line in the code, which validate the x509 certificate:

ServicePointManager.ServerCertificateValidationCallback = (sender, certificate, chain, sslPolicyErrors) => true;

This will accept all certificates, regardless of why they are invalid, which resolved the customer’s issue.

By validating the X509 certificate provided by the computer running Microsoft Exchange Server 2007 for SSL over HTTP, you help to provide a layer of security for the client application. You must validate certificates before you can start programming with Exchange Web Services proxy classes. If the callback is not set up, the first call will fail with a certificate error.

Happy troubleshooting!!

Part # 2 - Using C#.Net & Exchange Web Service (EWS) : How to create and send e-mail messages?

In this we will see how to create & send e-mail messages using Exchange Web Service (EWS). It’s pretty simple with EWS to do.

       // Create the Exchange Service Binding

        ExchangeServiceBinding esb = new ExchangeServiceBinding();

       // Add its relevant Credentials like user name, password, domain and URL

        esb.Credentials = new NetworkCredential(userName, Password, domain);

        esb.Url = @"https://myexchangeserver/EWS/Exchange.asmx";

        // CreateItemType and set its relevant properties/values

        CreateItemType request = new CreateItemType();

        // Select Message Disposition specified

        request.MessageDisposition = MessageDispositionType.SendOnly;

        request.MessageDispositionSpecified = true;

       // Create MessageType and set its relevant properties/values

        MessageType message = new MessageType();

        // Enter value for subject

        message.Subject = subject;

        message.Body = new BodyType();

        message.Body.BodyType1 = BodyTypeType.Text;

       // Enter value for body

        message.Body.Value = body;

        message.ToRecipients = new EmailAddressType[1];

        message.ToRecipients[0] = new EmailAddressType();

       // Enter ToEmailAddress

        message.ToRecipients[0].EmailAddress = toEmailAddress;

       // Select Routing Type

        message.ToRecipients[0].RoutingType = "SMTP";

        request.Items = new NonEmptyArrayOfAllItemsType();

        request.Items.Items = new ItemType[1];

        request.Items.Items[0] = message;

        try

        {

           CreateItemResponseType response = esb.CreateItem(request);

           // Determine whether the request was a success.

            if (response.ResponseMessages.Items[0].ResponseClass == ResponseClassType.Error)

            {

                throw new Exception(response.ResponseMessages.Items[0].MessageText);

            }

            else

            {

                Console.WriteLine("Item was created");

                Console.Read(); 

            }

          }

          catch(Exception e)

            {
