Why are links blocked in AKO email?

This is on your personal computer, right?

Mine does the same.

I have no problem with my government computer.

Also, AKO usually suspects most links are spam, so it blocks them. I think it automatically does it on Firefox, but the internet explorer at work works just fine.

It could be a security precaution. To make sure you're actually vetting the link before you click it.

Also, there are macros that can run in virus-ladden emails and automatically launch links which then "drive-by download" malware to your computer without consent.

If you're on AKO, the link won't open properly so no malware would be downloaded.

Well my experience with Networks in the Military is that they have recently added the site your trying to access to their Firewall list.
