In many countries, the start dates and end dates for daylight saving time (DST) change from year to year. Additionally, countries may change their policy of recognizing daylight saving time, or they may change the local time offset from Coordinated Universal Time (UTC).
Daylight saving time implementation varies from country to country. Some countries may not observe daylight saving time, whereas other countries may change the start dates and end dates for daylight saving time every year.
For more detailed information, please find this article which describes how to update a Windows-based computer to use the latest global time zone rules as of December 2007.
The following list shows some of the major changes that have occurred for daylight saving time:
• Argentina: DST is being introduced in Argentina.
• Brazil: There are different DST dates in Brazil.
• Canada: All provinces in Canada that use daylight saving time have adopted the same changes as the United States.
• Chile: There are different DST dates in Chile.
• Egypt: There are different DST dates in Egypt.
• Iran: DST is being reintroduced.
• Iraq: Iraq no longer observes DST.
• Israel: There are different DST dates in Israel.
• Mexico: Mexico has not adopted the DST changes that were made in the United States. Therefore, separate time zone definitions must be used for Mexico.
• Morocco: DST is being introduced in Morocco.
• Pakistan: DST is being reintroduced in Pakistan.
• Sri Lanka: The local time offset has changed from UTC+6:00 to UTC+5:30.
• United States: Beginning in the spring of 2007, the start dates and end dates for daylight saving time (DST) will change to comply with the Energy Policy Act of 2005. DST dates for 2007 in the United States and Canada will start three weeks earlier (2:00 A.M. on the second Sunday in March), and will end one week later (2:00 A.M. on the first Sunday in November).
• Uruguay: A new time zone has been created for Montevideo, Uruguay.
To obtain the list of time zones that have changed together with their DST start dates and end dates, use the information in the following Knowledge Base article:
942763 December 2007 cumulative time zone update for Microsoft Windows operating systems
Please find the differences among the following Outlook items:
•Appointment: A calendar item that users create for themselves and that has no attendees other than the organizer.
•Meeting: A calendar item for which there are attendees in addition to the organizer.
•Calendar item: An item on the user’s calendar. This can be an appointment or a meeting.
I found this wonderful article describes the optimization of memory usage on your computer that is running Exchange Server 2003. For example, if you have 1 gigabyte (GB) or more of physical memory (RAM) installed on a server that is running Microsoft Exchange Server 2003, you must make sure that Exchange 2003 can make efficient use of that memory. Please Note: Exchange 2003 performs an optimal memory configuration check when the store process starts. If the memory settings are not optimal, you will see event 9665 in Event Viewer. This message appears if one or more of the following conditions are true, as specified in the MSDN article.
It has many recommendations for each of the suggested settings.
Do you know why personal folder files (.PST files) are unsupported over a local area network (LAN) or wide area network (WAN) link?
The .PST files are not meant to be a long-term, continuous-use method of storing messages in an enterprise environment.
Although it is possible to specify a network directory or a Universal Naming Convention (UNC) path as a storage location for a .PST file, network usage is not meant to be a long-term, continuous-use method of storing messages in an enterprise environment. As you know that a .PST file is a file-access-driven method of message storage. File-access-driven means that the computer uses special file access commands that the operating system provides to read and write data to the file. This is not efficient on WAN or LAN links because WAN/LAN links use network-access-driven methods, commands the operating system provides to send data to or receive from another networked computer.
Other Behaviors of .PST Files over WAN/LAN Links
•All operations take longer.
• Write operations can take approximately four times longer than read operations.
• Outlook has slower performance than the Exchange Client
Suggested alternatives: Can suggest/make use of,
1) .OST files 2) Microsoft Windows Terminal Services
For more information, please refer the following MSDN article.
As you know, the Messaging API (COM-like API) that provides access to the contents of messaging stores. CDO 1.2.1 (Collaboration Data Objects, version 1.2.1) is a package providing access to Outlook-compatible objects through a COM-based API. Using either CDO or MAPI, a program can connect to a MAPI store, and then perform operations against that store.
Starting from Exchange 2007, neither the Messaging API (MAPI) client libraries nor CDO 1.2.1 are provided as a part of the base product installation. As a result, there is functionality missing that many applications depend on. Microsoft Exchange MAPI and CDO 1.2.1 provide access to these API's.
From Exchange 2007, Microsoft will distribute the MAPI client libraries and CDO 1.2.1 as a Web download.
You can download it from Microsoft Download Center.
Please note: This version is now compatible with Windows Vista and Windows Server 2008. Note also that this web release follows the Microsoft Lifecycle policy of Exchange Server 2003, which goes into Extended Support in April 2009.
What is MX Record?
MX stands for Mail Exchange Records.
Where it's used ?
MX records are used in DNS records(or Zone files) to specify how email should be routed.
What is SMTPDiag?
SMTPDiag is a troubleshooting tool designed to work directly on a Windows server with IIS/SMTP service enabled or with Exchange Server installed.
What is it used for?
How to use it:
commandprompt:\> SMTPDIAG “sender address” “recipient address” [-d target DNS] [/v]
Argument & its definition: sender address : Required. Address of a local mailbox. Used to verify SMTP submission and check inbound DNS.
recipient address: Required. E-mail address of remote mailbox you are trying to send mail to. Used to verify DNS, and remote mailbox availability.
-d target DNS :Optional. IP address of target DNS server to use to look up remote MX (mail exchange) records for testing. This is configured as an external DNS server in Exchange. Please note that the external DNS setting is not available for Internet Information Services (IIS) SMTP.
/v: Optional. Displays additional information about each test.
/?: Displays Help
Please Note: The results will be color coded in the syntax. It will have the following colors and its definition:
White text indicates action being taken. Gray indicates informational results Green indicates a successful test result. Red indicates a failed test result.
You can download the tool from Microsoft Download Center.
People today depend on being able to stay in touch no matter how close or how far away they are from the office or home.
For businesses, that means a host of challenges to make sure their communications foundation is secure, reliable and accessible across many mobile devices – from notebooks to PDAs and smartphones.
Microsoft has been helping companies overcome those challenges and streamline their communications infrastructure with Microsoft Exchange Server 2007, and the popularity of Exchange Server 2007 among corporations has influenced many mobile device makers to support Exchange right out of the box.
Today, Apple announced it plans to join the list of mobile device makers that offer built-in support for Exchange mobile e-mail, licensing Microsoft Exchange ActiveSync for the iPhone.
For a detailed information, please find the following article, which was represented by Terry Myerson, corporate vice president for Exchange, talks to PressPass about the importance of the new agreement between Microsoft and Apple to offer built-in support for Exchange on the iPhone, and the increasing popularity of Microsoft Exchange Server 2007 among mobile professionals.
Welcome to troubleshooting performance issues - MS Outlook Performance Series - Part 6
One of my customer reported that he is facing issue with Outlook 2007 & Windows Vista environment, as he can't open the .pst files.
He get the following error: <sample>.pst file could not be opened. The file may not be compatible with this version of Outlook or it may be corrupted.
End of the research, we found the issue happens due to the mail file is in an encrypted folder.
To work around this problem, we need to make use of Inbox Repair Tool (Scanpst.exe) to repair the personal mail file.
Please find the following http://support.microsoft.com/kb/934545 which describes the issue, causes and its resolution in-detail.
Welcome to troubleshooting performance issues - MS Outlook Performance Series - Part 5
Recently I was working with one of my customer, we came across a strange issue.
He has MS Outlook 2007 which was running on Windows Vista. He updated that it takes long time to download an e-mail message from a POP3 server in Microsoft Office Outlook 2007. Whenever they download a mail with attachment (for example .5 megabyte (MB) message), the download takes more than one hour.
Additionally, when they send e-mail messages by using the SMTP server of their Internet service provider (ISP), they get time out issue and also got the following error message:
Task 'Main - Sending and Receiving' reported error (0x800CCC0F) : 'The connection to the server was interrupted. If this problem continues, contact your server administrator or Internet service provider (ISP).'
At the end of the research, we found the issue happens due to "TCP Scaling", a new feature introduced in Windows Vista. This problem occurs if a network hardware device, such as a router, does not support TCP Window Scaling.
Please find the following article http://support.microsoft.com/kb/935400, which describes the issue and its resolution in-detail.
Welcome to troubleshooting performance issues for MS Outlook 2007 Series - Part 4
If the .pst file or the .ost file shuts down incorrectly, you may receive one of the following error messages the next time that you start Outlook:
Error message 1: Outlook cannot open the data file filename until it has been checked for problems.
Error message 2: Microsoft Office Outlook’ exited without properly closing your Outlook data file ‘drive:\Users\username\AppData\Local\Microsoft\Outlook\outlook.ost’. ‘Microsoft Office Outlook’ must be restarted. If this error message recurs, contact support for ‘Microsoft Office Outlook’ for assistance.
If you receive one or more of these error messages, you may experience performance issues until Outlook finishes the reconciliation process for the .ost file or for the .pst file. The following gear icon is displayed in the status bar while Outlook checks the data file in the background:
When this icon disappears, the .pst file or the .ost file is reconciled. If you exit Outlook while the gear icon is present, reconciliation must restart the next time that you run Outlook. It's recommended that you leave Outlook running until the gear icon disappears before you exit Outlook.An incorrectly shut down .ost file or .pst file may occur for one of the following reasons:
If you see this issue frequently, and you have to exit Outlook shortly before you shut down your computer, it may be better to shut down Windows while Outlook is still running.
When we make use of Exchange Server 2007 SP1 & Windows Powershell, if we have a requirement to sort the mailboxes based on their size on the ascending order, then try this command:
Get-MailboxStatistics -Server Servername | Sort-Object -Property TotalItemSize | Format-Table DisplayName,TotalItemSize

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

In this series, we will learn "How to systematically release the objects - Add-in's for Outlook 2003 & Outlook 2007 ?". I found this MSDN article which describes how all Outlook add-ins should systematically release their references to Outlook objects when they are no longer needed. Failing to systematically release reference to Outlook objects can prevent Microsoft Office Outlook 2003 & Outlook 2007 from shutting down properly.
For more information about this problem that affects managed add-ins written for Outlook 2003 using Visual Studio .NET, see KB 317109: Office application does not quit after automation from Visual Studio .NET client.
Please find Mstehle's blog: OOM.NET: Part 2 - Outlook Item Leaks (Outlook + OOM + .Net Issues), which describes in detail and has the resolution to solve the issue...
When you try to start Microsoft Office Outlook 2003, the program does not start. Additionally, you receive the following error message:
Do you know....this issue may occur if you install and then uninstall Microsoft Office Outlook 2007 Beta 2 on a computer that has Outlook 2003 installed.

Welcome to Outlook Programming series # 8
In this series, we will learn "How to update existing items in an Outlook folder to use a new custom form?". I found this MSDN article which describes programatically how to update existing items in an Outlook folder to use a new custom form?
This article describes how to update items in an Outlook folder so that those items open using a different form than the form that the items are currently associated with.
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.
Please view this useful MSDN KB Article. It has the information about the issue, its cause, re-solution for this issue
When you send an item that is based on a custom form, the form is not sent and you receive the following error message: "Operation Failed"
This issue will happen if, a Recipient field on the custom form is configured with an initial value and with the Calculate this formula automatically option for that value.
Please view this useful MSDN KB Article. It has the information about the issue, its cause, workaround solution for this issue.
