Email stopped working in Office 365

This email account has stopped working in Outlook 365.
All settings are correct, so deleted it.
When I try to re-add it I get a "we cannot log into the incoming (IMAP) server.
I am using the following settings:

Incoming Server Name - imappro.zoho.eu

Port - 993

Require SSL - Yes

Outgoing Server Name = smtppro.zoho.eu

Port - 465 with SSL

I know the password is correct as I can get into the account online
