SYMPTOMS
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:  The Outlook Group Policy settings may not be applied correctly.

For example, the following Group Policy settings under Exchange Settings in the Outlook 2003 administrative template (.adm) are not applied.

When this problem occurs, the offline folder file may remain in ANSI format. The Outlook Group Policy settings are applied, but the user is prompted to create a new offline folder file the next time that the user starts Outlook 2003.

For example, the user may be prompted with the following message the next time they start Outlook 2003:

Outlook must create a new Offline Folder file (.ost) to comply with a policy set by your administrator. To start creating the Offline Folder file now, click OK. Outlook will synchronize your data. This might take a long time. To create the file later, click Cancel.

If the user clicks OK, the Offline Folder Settings dialog box appears.

If the user clicks Cancel, they receive the following message:

The Offline Folder file C:\ \Outlook.ost cannot be used in this profile. Your administrator has set a policy that lets you use only those Offline Folder files that provide more storage capacity and support multilingual Unicode data.





CAUSE
This problem occurs because the Outlook 2003 Group Policy detection logic does not correctly detect the existence of the &quot;Exchange Unicode Mode - Ignore OST Format (IgnoreOSTFormat)&quot; Group Policy setting. Group Policy settings that force clients to use a Unicode offline folder (.ost) file are not applied.

After you install this hotfix, follow the steps that are listed in the &quot;More Information&quot; section.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the &quot;Applies to&quot; section. This problem was first corrected in Office 2003 Service Pack 2.



MORE INFORMATION
Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall your operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.

To enable this hotfix and to set the SilentOSTFormatChange registry key, follow these steps:  Quit Outlook 2003. Click Start, click Run, type regedit in the Open box, and then click OK.</li> Locate and then click to select the following registry subkey:

HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\11.0\Outlook\EMSP

</li> After you select the subkey that is specified in step 3, point to New on the Edit menu, and then click DWORD Value.</li> Type SilentOSTFormatChange, and then press ENTER.</li> Right-click SilentOSTFormatChange, and then click Modify.</li> In the Value data box, type 1, and then click OK.</li> On the File menu, click Exit to quit Registry Editor.</li></ol>

Additional administrator information
This hotfix updates the Group Policy detection logic for policy enforcement. When the &quot;Exchange Unicode Mode - Ignore OST Format&quot; Group Policy setting contains a value, the detection logic runs correctly and the policy is correctly enforced.

Additionally, this hotfix adds the new &quot;Exchange Unicode Mode - Convert Format Silently&quot; (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 Setting
To enable the SilentOSTFormatChange Outlook Group Policy setting by using the Outlook 2003 Group Policy administrative template file (OUTLK11.adm), follow these steps: <ol> Log on to a domain controller by using an account that has administrative permissions.</li> Right-click the OUTLK11.adm file, click Open With, and then click Choose Program.</li> In the Open With dialog box, click Notepad, and then click OK.</li>  In Notepad, scroll to the end of the text. Then, enter the new registry key and a description before END CATEGORY.

For example, the following code adds the SilentOSTFormatChange Outlook Group Policy setting to the Outlook Group Policy template. POLICY &quot;Exchange Unicode Mode - Convert Format Silently&quot; KEYNAME &quot;Software\Policies\Microsoft\Office\11.0\Outlook\EMSP&quot; PART &quot;Convert to required OST format silently&quot; CHECKBOX VALUENAME SilentOSTFormatChange VALUEON NUMERIC 1 VALUEOFF NUMERIC 0 END PART END POLICY

END CATEGORY END CATEGORY </li></ol>

After you import the OUTLK11.adm file, you can set the following policies:

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.
