Background information

If Word is the Outlook e-mail editor, creating a new message in Outlook starts Word and loads PDFMOutlook.dll. PDFMOutlook.dll is an Adobe COMAddin for Outlook that is used by the Attach As PDF feature for Outlook. As part of increased security introduced in the Outlook Security Features Administrative Package, the Outlook object model used by third-party COMAddins to access Outlook functionality is protected by an object model guard. If you access e-mail on a Microsoft Exchange server that is set to pass security settings to users and the Outlook Security Features Administrative Package is installed, PDFMOutlook.dll encounters the guard when it loads and the Outlook returns the warning (even though the add-in doesn't access the address book).
