The types of files that are blocked or allowed when a user sends or receives a message are
specified in the Entourage 2008 Attachment Policy. For more information about the Attachment
Policy, see Attachment file types in Entourage 2008
in the Office 2008 Technical Reference section.
If you want to change the Attachment Policy, create a supplementary .plist file as described in the
following procedure. Any changes made to the default Attachment Policy .plist file are subject to
override during application updates. Changes to the supplementary file will not be affected by
updates.
Create a supplementary Attachment Policy .plist file
1. Hold down CONTROL and click the
Microsoft Entourage icon.
2. Click
Show Package Contents.
3. Double-click
Contents, and then double-click Resources.
4. Click
AttachmentPolicy.plist, and then press +D to duplicate the file.
5. Drag the duplicate file either to /Library/Preferences (to take effect for all users on the
computer) or to /Users/username/Library/Preferences (to take effect for a single user).
6. Rename the file
com.microsoft.entourage.attachmentpolicy.plist.
7. Open the file in your property list (plist) editor.
8. Delete all individual String entries, but do not delete the Dictionary and Array entries.
9. In the
AllowedAttachments list, create String entries for any file types that you want to
allow.
You can specify a file type by using a FilenameExtension, a MIMEContentFileType, or a
MacOSFileType.
Create the String entry as a child entry under the corresponding Array type.
10. In the
UnsafeAttachments list, create entries for any file types that you want to block.
It is not necessary to specify file types that are already blocked in the default .plist file.
11. Save, and then close the file.
12. Quit, and then restart Entourage.
Note When specifying the file extensions, do not precede the extension with a dot (.). For
example, if you want to include the extension asp to your
AllowedAttachments list, just specify
asp instead of .asp.
