I'm posting on behalf of a customer.
The customer has Windows 8 and is trying to use the Metro Mail app. He is trying to both send and receive emails with his Hostgator Server email address. It allows him to receive his emails but not to send them. He has tried both 25 and 587 STMP ports but has the same issue with both. After a few seconds the email he is composing merely goes to the Drafts bin.
He has tried uninstalling and reinstalling the app but it does not seem to make a difference. SSL is not checked, though he has tried with both settings and that does not seem to make a difference for him either. He has tried running the Modern UI App Troubleshooter but it has not produced any results to go by to fix the problem. He has also tried to manually sync his accounts but again, attempts at fixing the problem have thus far been unsuccessful.
He has since added a Gmail account to his Mail app as well which works fine but his original email is still experiencing the same issue.
Any workarounds or fixes for this particular problem?
