SMTP Server connection not working with Outlook 2013

SMTP Server connection not working with Outlook 2013

Hi,
I configured my Outlook for using my zoho mail in my Outlook programm.
I did everything correct. I used Pop3 - pop.zoho.eu and smtp - smtp.zoho.eu
 .... and change the port for pop3 to 995 and smtp to 465
https://www.zoho.com/mail/help/pop-access.html
Everything like in this forum post. After that the Outlokk programm is checking the connection.
Pop3 worked fine but I always get a issue with the smtp server:
Outlook isn´t able to connect to the smtp server. Please contact your internet provider.
You can see the error in the picture 1.png.

Please help me! Zoho is a great service and Outlook too. I want to use them both!
