Set up Email Pro account on Outlook MAC

Hello,
I'm trying to set up my Email pro account on my Outlook (Mac)
I've obviously read the tutorial about it and can't make it work anyway !

What i'm sure of :
1. The IMAP username (my full email adress)
2. The server to connect on : pro1.mail.ovh.net
3. The Password (tested on the Webmail - and fonctionnal)
4. The ports (993 & 587 - if I trust the tutorial)
5. SSL connection recommanded

can't make it work... either on Outlook for MAC, neither on Outlook iOS (using the proper ports for Mobile)

But it's working on Mail, the native Mac mail app

Error. : "Impossible to connect. Check outgoing server parameters, server name, ports, and protocol"

Does anyone experience similar issue ? I'm starting to get mad 😡
