Back with another issue in my outlook 2003 experience.

I am replying to an email as I usually do many times a day and all of the sudden when I click on send I get an error msg that says, "The Operation Failed".

So I keep trying and keep getting the same msg. I have seen this happen to some people when they hit send/recieve, but not just when replying to an email.

Something doesn't seem to be right here and I was wondering if anyone came across this in the past? Other times everything in outlook seems to be fine, but why would it fail to send an email that is no different than any other email that I or anyone else sends throughout the day.

Do I need some sort of fix for outlook or word (since that is the email editor) or perhaps repair outlook or something else?

Any light you can shed would be great as I am stumped currently. Thanks.
