SUMMARY
This article summarizes how the Microsoft Outlook E-mail Security Update may affect third-party products if those products are related to Outlook or use other messaging functionality. For more information about other types of issues when you apply the Outlook E-mail Security Update, see the &quot;References&quot; section.



MORE INFORMATION
The Microsoft Outlook E-mail Security Update significantly changes the way that Outlook handles attachments, and the way that Outlook handles requests for programmatic access. Because of the new design, any feature or program that uses any of the following features may behave differently after you install the update:
 * Attachments
 * The Outlook object model
 * Simple Messaging Application Programming Interface, or Simple MAPI

Synchronization Software
After you install the security update, you may experience issues with synchronization software. When you synchronize a Handheld PC (H/PC), cellular phone, or other device, you are prompted to allow the program access to your address book and contacts. Viruses can spread by sending copies of e-mail messages to people that are listed in your address book, and you must allow access to your address book before the synchronization can continue.

Many synchronization utilities will generate warning messages before you can synchronize. However, some synchronization utilities may not work before or after you are prompted to allow access to the address book information. After the security update is released, this article will contain information about specific software and how the software is affected by the security update. If you are using software that interacts with Outlook and it does not function even after you allow access to the address book information, Microsoft recommends that you first check with the manufacturer of the software to see if an update is available.

After Microsoft Product Support Services (PSS) is able to verify the known issues with third-party products, this section will contain information about other software that is affected after you apply the Outlook E-mail Security Update.
