I was recently tring to bypass outlook security for a proper business related purpose and
found it very difficult.(managed it though with tampa bays help (great guy))

Although some exploits still exist The proper full office XP and Office 2000 with proper active directory and patched up to SP3 seem pretty stable and secure.

What most people don't seem to realise that use unix is that not many people bother looking for security exploits etc because not many businesses use it on local machines. (ones with users on them)

People who slag of microsoft for being sloppy and insecure must remember that they still have a much wider user base than any other os and hence more bell ends looking for problems.

I use redhat 9 and it is secure but not many companies use it.

I mean its like comparing breaking into a car to steal a stereo and breaking into a tank.

Its more practical to own a car because its more compatible with whats available.
