You apply a Microsoft Office Outlook 2003 Group Policy. If the policy contains a setting that forces Microsoft Outlook clients that are using Cached Exchange Mode to only use a Unicode offline folder (.ost) file, you may experience one of the following symptoms:
This problem occurs because the Outlook 2003 Group Policy detection logic does not correctly detect the existence of the "Exchange Unicode Mode - Ignore OST Format (IgnoreOSTFormat)" Group Policy setting. Group Policy settings that force clients to use a Unicode offline folder (.ost) file are not applied.

Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs.

To enable this hotfix and to set the SilentOSTFormatChange registry key, follow these steps:
Additional administrator informationThis hotfix updates the Group Policy detection logic for policy enforcement. When the "Exchange Unicode Mode - Ignore OST Format" Group Policy setting contains a value, the detection logic runs correctly and the policy is correctly enforced.
Additionally, this hotfix adds the new "Exchange Unicode Mode - Convert Format Silently" (SilentOSTFormatChange) Outlook Group Policy setting. The SilentOSTFormatChange Group Policy setting enables the new offline folder file to be renamed automatically without prompting the user.
Set and enable the SilentOSTFormatChange Outlook Group Policy SettingTo enable the SilentOSTFormatChange Outlook Group Policy setting by using the Outlook 2003 Group Policy administrative template file (OUTLK11.adm), follow these steps:
As soon as you set the policies, the Outlook clients are forced to use a Unicode offline folder file. This Unicode offline folder file is now automatically created, and you will be required to perform a full sychronization so that Outlook can be used in Cached Exchange Mode.

The following registry subkey is created when you apply these policy settings:
You can use this registry subkey with the IgnoreOSTFormat=2 setting. As soon as this subkey is set to this setting, Outlook users can choose to delay full synchronization.
This subkey lets an Outlook client that is using a low-bandwidth connection choose whether to perform a full sychronization.
After you install this hotfix, if the user chooses to enable the policy enforcement for the current session, a new offline folder file is automatically created for the user.
Note Typically, you must log off and then log back on to Microsoft Windows two times before the offline folder file policy settings are enforced. You must do this because your account is logged onto the offine folder file before your account is logged on to the Microsoft Exchange Information Store service when Outlook is run in Cached Exchange Mode.
