Running zoho account within Outlook

I have an EU zoho mail account.

I can't seem to connect the zoho account into the Outlook App windows 10

Have tried all the options

IMAP

incoming imappro.zoho.eu and imap.zoho.eu

outgoing smtp.zoho.eu

Always get the following error

We couldn't log on to the incoming (IMAP) server.

Any advice please.

Thanks

Mike
