Outlook has increased security around the Outlook Object Model, which many third-party software companies use to integrate their product with Outlook. These new security enhancements may now cause you to be prompted to allow the programs access to your Outlook data.
In some cases, the third-party software companies may provide updated versions of their software that will not cause you to be prompted for access to your Outlook data. For technical information regarding this change, see the Outlook Object Model section later in this file and the Microsoft Developer Network (MSDN) Web article titled Important Security Notes for Microsoft Outlook COM Add-In Developers.

When Outlook receives a message containing a form definition, the item is considered to be a one-off form. To help prevent unwanted script and controls from running in one-off forms, Outlook will not load ActiveX controls in one-off forms by default. This behavior can be controlled by administrators using one of the following registry settings:
HKCU\Software\Policies\Microsoft\Office\11.0\Outlook\Security
HKCU\Software\Microsoft\Office\11.0\Outlook\Security
AllowActiveXOneOffForms (DWORD)
not present - Only load controls that are listed below. (default)
0 - Only load controls that are listed below.
1 - Allow only safe controls.
2 - Allow all ActiveX controls.
The following controls can be used in one-off forms:

If you use Outlook 2003 and then use any Collaboration Data Objects Library (CDO) 1.2x application, such as Microsoft Outlook Web Access for Microsoft Exchange Server 5.5, Exchange Server may stop working if you have not previously installed the hotfix mentioned in the applicable Knowledge Base (KB) article below.
Note Versions of Outlook Web Access for Exchange Server later than Exchange Server 5.5 are not affected because the later versions do not use CDO. However, other CDO-enabled applications are affected unless the hotfix has been installed for the version of Exchange Server that you are using.
For more information about this issue, see the KB article applicable to the version of Exchange Server that you are using on Microsoft Office Product Support for Office Users.

In addition to inheriting the Outlook 2002 Object Model Guard behavior, Outlook 2003 blocks code that attempts to access certain properties of the Outlook object model for security reasons. These additional blocks may cause programs that worked with previous versions of Outlook to encounter security blocks. The additional properties that have been blocked in Outlook 2003 are:

Nonrecurring meetings
More than one nonrecurring meeting request can link to the same Meeting Workspace if the workspace has not previously been linked to a recurring meeting series.
Recurring meetings
Using delegates
To permit an Outlook delegate to create a Meeting Workspace for you, the delegate must first have permissions on the Microsoft Windows SharePoint Services Web site where the Meeting Workspace will be created.

To receive Microsoft Windows SharePoint Services alerts in Outlook, you need to add the SharePoint server’s address to the registry in the following location:
HKEY_CURRENT_USER/Software/Microsoft/Office/11.0/Common/Security/Trusted Alert Sources "siteurl" (REG_SZ) = 1
Where the "siteurl" string would be "www.fourthcoffee.com" if the SharePoint site was http://www.fourthcoffee.com.

If you open the Rules and Alerts dialog box when using Microsoft Windows Server 2003 as your operating system, alerts that were previously created on intranet Web sites will not be displayed in the Alerts list. Any new alert sources that have not been verified will be permanently deleted from the Alert Source list. To work around this problem, add the SharePoint sites to the list of intranet sites or trusted sites in Microsoft Internet Explorer.
