Odd Ports showing up on Security Audit

Hello -

At work we just started Egress filtering and have noticed one computer communicating on port 8080 (using Microsoft Outlook) and I can not figure out why.. Any have any ideas?

Also, We have another computer communicating on port 81 via Microsoft Outlook.

I am thinking it might be virus related, because there is no good explination as to why they are communicating on these ports.

Any insite would be greatly appreciated.
