All the versions of MS Outlook after Outlook 2000, include a security feature that blocks attachments that can put your computer at risk for threats or viruses. For example, If you have received some emails with attachments whose extension is .exe, .msi, etc, then you will get a warning message \u201cOutlook blocked access to the following potentially unsafe attachments\u201d. Microsoft Outlook considers these types of attachments as unsafe and blocked them by default.\u00a0<\/p>\n\n
