Please verify that port 25 is not blocked. Furthermore, if it did not work try using another port. That is my suggestion for now. Let me know if it did not work.

And if it does, you also need to know on which port. The default port in Outlook for SMTP is 25, but in Google for example SSL is supported on port 465. Also your mail server might support other security protocols for SMTP, like TLS. Again Google establishes TLS connection on port 587. So really, you need to go your mail provider support and obtain this information from them. You can't really guess what combination of protocols and ports they are using. All these settings in Outlook can be changed at: File -> Info -> Account Sett
