Some attachments are not blocked by the Outlook E-mail Security update in Outlook 2000 (273507)


The information in this article applies to:

  • Microsoft Outlook 2000, Service Release 1 (SR-1)
This article was previously published under Q273507

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.
