    Welcome to troubleshooting performance issues in MS Outlook Series - Part 2

    Do you face any one of the following issue, when you work with MS Outlook 2007?

    When you try to,

    • read e-mail emessages ?
    • move e-mail messages?
    • delete e-mail messages?

    Do you face Microsoft Office Outlook 2007 momentarily stops responding?

    Do you know, these symptoms are most noticeable during mail delivery or during synchronization. These symptoms become more pronounced as store size increases. They are more likely to occur when the size of the .pst file or the size of the .ost file approaches 2 gigabytes (GB). Additionally, they are more pronounced in a very large .pst file or in a very large .ost file that is 4 GB or larger. 

    For more information, please find this wonderful article, which talks about how to troubleshoot the performance issues in Outlook 2007 and with respect to larger .pst or .ost files.

    Exchange Web Service: Web Services Message cycle

    • 0 Comments

    Exchange Web Services Message cycle 

    • When a client application requests information from the Exchange store, an XML request message that complies with the SOAP standard is created and sent to the Exchange server.
    • When the Microsoft Exchange server receives the request, it verifies the credentials that are provided by the client and automatically parses the XML for the requested data.
    • The server then builds a SOAP response that contains XML data that represents the requested strongly typed objects and their properties.
    • The XML data is sent back to the client application in an HTTP response.
    • The client application then deserializes the XML and uses the data to reform the strongly typed objects.

    Exchange Server Development Technologies - Series # 1 - Exchange Rules

    • 0 Comments

    Welcome to Exchange Server Development Technologies - Series # 1  

    In this series, we will discuss about the Exchange Rules. This topic provides information about using Exchange Rules to develop messaging applications. 

    • Exchange rules are typically used to specify user-defined actions that are to be performed on messages that arrive in folders of the user's mailbox.
    • In addition, it is possible to use a set of predefined rules on Public Folders 
    • Exchange Server uses rules on mailboxes and other folders to automatically execute actions on objects in the folders.
    • You can use rules to develop applications that carry out predefined or custom actions, even at times when the application is not running.
    • Rules can be performed on the Exchange store (server-side) or on Microsoft Outlook (client-side, deferred action rules).

    For more detailed information, please find this MSDN documentation.

    Outlook Custom form Issue: Listbox control unexpectedly adds new value

    • 1 Comments

    When using a custom form containing a ListBox control, Outlook unexpectedly adds a new possible value to the control.

    Do you know....this behavior is due to the storage limitation of Keywords fields. If the control is bound to a field of type Keywords and you select a number of possible values in the control, the field may exceed its 255-character maximum length. This causes the last value to be truncated. Because the custom Keywords field now contains a new value that is not one of the options in the control, Outlook adds this new value to the list of possible choices in the control.

    General : What is a Digital Signature?

    • 0 Comments

     A digital signature is used to authenticate (The process of verifying that people and products are who and what they claim to be. For example, confirming the source and integrity of a software publisher's code by verifying the digital signature used to sign the code.) digital information — such as documents, e-mail messages, and macros — by using computer cryptography.

    Digital signatures helps us, 

    To establish the following assurances:

    • Authenticity   The digital signature helps to assure that the signer is who they claim to be.
    • Integrity   The digital signature helps to assure that the content has not been changed or tampered with since it was digitally signed.
    • Non-repudiation   The digital signature helps to prove to all parties the origin of the signed content. "Repudiation" refers to the act of a signer's denying any association with the signed content.

    To make these assurances, the content must be digitally signed by the content creator, using a signature that satisfies the following criteria:

    • The digital signature is valid (Refers to the status of a certificate checked against a certificate authority's database and found to be legitimate, current, and not expired or revoked. Documents signed by a valid certificate and not altered since signing are considered valid.).
    • The certificate (A digital means of proving identity and authenticity. Certificates are issued by a certification authority, and like a driver's license, can expire or be revoked.) associated with the digital signature is current (not expired).
    • The signing person or organization, known as the publisher, is trusted (The developer of a macro that is trusted by you on your computer. The trusted publisher is identified by the certificate that they used to digitally sign the macro. Also known as a trusted source.).
    • The certificate associated with the digital signature is issued to the signing publisher by a reputable certificate authority (CA) (A commercial organization that issues digital certificates, keeps track of who is assigned to a certificate, signs certificates to verify their validity, and tracks which certificates are revoked or expired.).

    Outlook Programming Series # 5 : How to build an Outlook 2007 Form Region with a Managed Add-In?

    • 0 Comments

    Welcome to Outlook Programming series  # 5

    In this series, we will learn "How to build an Outlook 2007 Form Region with a Managed Add-In?". I found this wonderful article, wrote by Ryan Gregg, which describes programatically how to build a form region with a Managed Add-in and Outlook 2007 environment. It covers the creation of a sample Outlook add-in that displays transport header information in a form region on e-mail items, along with free downloadable samples...:)

    As we know you can create and run forms with form regions without a COM add-in, but using a COM add-in has the benefit of supporting custom business logic or advanced functionality in the form regions.

    Note: This article assumes that you have some knowledge of COM add-ins and that you know how to build, deploy, and install a managed COM add-in that is written in Microsoft Visual Basic or Microsoft Visual C#. You should be familiar with the Outlook object model, and should have at least some basic knowledge of the Microsoft .NET Framework and COM interoperability.

    Outlook Add-in : What is a COM Add-in? What You Need to Create a COM Add-in?

    • 1 Comments

    What is a COM Add-in?

    COM add-ins are a feature in Microsoft Office and are supported by all Office programs, including Outlook.

    Key benefits of COM add-ins include:

    COM add-ins run in-process with the host program, so custom code generally runs faster than code implemented in Visual Basic for Applications.

    The basic COM add-in architecture is consistent across all Office programs, whereas in previous versions of Office, each program had its own add-in architecture.

    You can create one COM add-in to use with more than one Office program.

    What You Need to Create a COM Add-in?

    In addition to Outlook, you need one of the following development environments to create a COM add-in for Office or Outlook:

    Visual Basic 5.0 or later (Visual Basic 6.0 is preferred)

    Microsoft Office Developer, which includes the ability to compile a Visual Basic for Applications project into a Dynamic Link Library (DLL)

    Any other COM-compliant development environment, such as Microsoft C++ or Microsoft J++

    The Click event is the only event that Outlook supports for controls. However, for some controls the Click event may not fire if the control is bound to a field, or it may not fire at all.

    Note: This articles summarizes whether or not the Click event will fire under various circumstances.
