I am having a strange problem to sending emails outside(email@example.com). But no problem to receive emails.
I ve 10 PC’s. 9 of them are using outlook & working nicely. So, It’s not SMTP (outgoing server) problem.
But suddenly 1 of them totally blocked to sending emails only (firstname.lastname@example.org). I tested another PC creating the same account, but its working (send/receive). So, I think problem in the outlook configuration in that PC.
So, any one pleaes help me…
