Summary: You are using Outlook Express as your email client and you receive an email with an attachment but Outlook Express will not allow you to open or save the attachment. This happens to most but not all attachments. This built-in security feature is enabled by default in Outlook Express and also affects the PDF invoice that clients receive from CaribServe.

This issue occurs if the "Do not allow attachments to be saved or opened that could potentially be a virus" option is enabled in the security settings of Outlook Express. By default, the "Do not allow attachments to be saved or opened that could potentially be a virus" option is enabled in Outlook Express 6 SP1. Any e-mail attachment with a file type that is reported as "unsafe" is not downloaded, and access to the attachment is removed.

Resolution: As a customer of CaribServe, we expect out to abide to the terms and conditions set forth in our General Terms and Conditions (GTC) as well as our Acceptable Usage Policy (AUP). One of the requirements for being a good standing member of our service is that you must have an up-to-date anti-virus program running on your computer. As such, this security feature of Outlook Express is useless and can thus be disabled.

To turn off the "Do not allow attachments to be saved or opened that could potentially be a virus" option:
  1. Start Outlook Express.
  2. On the Tools menu, click Options.
  3. Click the Security tab, click to clear the Do not allow attachments to be saved or opened that could potentially be a virus check box under Virus Protection, and then click OK.
  4. Close Outlook Express.
  5. Start Outlook Express.
  6. You should be able to open and save your attachments from Outlook Express.
