SYMPTOMS
When you use the Microsoft Outlook E-mail Security update, Outlook blocks access to potentially unsafe file attachments. Microsoft Access uses potentially unsafe files with the extensions .mda and .mdz, but these extensions are not blocked by the security update.



CAUSE
This behavior occurs because both the .mda and .mdz file extension are not included in the internal list of potentially unsafe attachment types.
