hey im having the same trouble with my pc and till today i got no solution for it, so i look for it over the web and found this forum and i didnt understand what the other guy said u, so did u get a solution for the problem? if so can u tell me what u did, i have tried updating windows, outlook, everything, i just recently bought a new antivirus; panda (i had norton but according to it no viruses were on my pc), it was great it found lots of virus(20+-), spywares, etc.
so the only thing that i can think its that some virus its being attached to my outgoings and thats why outlook does not allowed me to send the email, i downloaded incredimail and the same.
ill appreciate if u tell me what u did with ur outlook if possible answer me to the_wu_jr87@hotmail.com
if anyone knows what to do please tell me asap
