I unable to attach a PDF (Acrobat Pro 9 - CS5) to Mac Outlook 2011. The following error message shows up:

Error message:

An error occurred while trying to create a mail document. Acrobat is unable to complete your request.

The default email program is set to Outlook. It’s working fine for Apple Mail. As I found out this has been a long-term bug within Acrobat <-> Outlook. Is there a workaround for this? I really need to send PDF to Outlook. Any help would be grateful. Thanks.
