Sending and Recieving Not working

[Angie]

I am currently using microsoft outlook 2002. I was doing
fine with sending and recieving emails until about 2 weeks
ago. I am getting eror messages saying that some of my
emails did not reach the recpients, with no spcific
reason. The weird thing is, I have sent these people
emails all the time before. None of my settings have been
changed at all. The funny part is that some people even
try to email me and there emails get bounced back to them,
with the same eror messages that I get. Can anyone help
me!

Thanks
Angie
