I can’t open incoming faxes because MS Outlook says the attachment is unsafe.

The files we send don't contain any viruses. They are safe, and comply with standards for email file attachments.

This problem is caused by a recent upgrade of Microsoft applications in your system. (For instance, some configurations of Outlook.)

To bypass this limitation, you just have to modify your Outlook client settings as follows:

  1. open Outlook
  2. choose "Options" from the "Tools" menu
  3. click "Protection"
  4. deselect the box "Do not save or open attachments that might contain viruses".
  5. Click "Apply" to confirm the change and then "OK".
