Having problems opening attachments in Outlook Express?
With Outlook Express 6, Microsoft has added an additional feature to prevent customers from infecting their machines with viruses. Any e-mail attachment with a file type that is reported as “unsafe” is not downloaded, and access to the attachment is removed.
If you receive this error message when viewing an email in Outlook Express, here is how to fix it:
1. Launch 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.
To better protect yourself from viruses, it is a good idea to leave this option checked unless you definitely want to open the attachment or have problems opening most or all attachments.
