IMAP Server no longer connecting

IMAP Server no longer connecting

Hi,

I can no longer get Outlook to work with my zoho email business account.

I have been using the settings below for some time and it worked, but now it can't seem to connect to the IMAP server. Has something changed zoho's end?

I have tried re-adding my rob@ account and it just says it can't connect to the IMAP server. 

Incoming Server (IMAP): 993
imappro.zoho.eu
SSL/TLS

Outgoing Server (SMTP): 465
smtp.zoho.eu
SSL/TLS

Username is my email and password is my email password which I've reset and know to be correct. 

Please advise.
