|What THX 1138 says makes very good sense.|
You don't need any form of Outlook or email program in order to go online. Doing things in that area should not prevent you getting an internet connection, Wireless or Ethernet.
In fact, although very dated, Outlook Express still works fine on XP for anyone who still cares to use it. It's on my XP (relegated to the spare room) and still working fine.
Always pop back and let us know the outcome - thanks
