I'm trying to add my zoho email to my outlook app on the ipad but it just says username/password invalid.

I know its correct as I can login to webmail fine.

Two factor authentication is OFF.

Tried via imap using imappro.zoho.eu  ( I'm using my own domain)

also tried via exchange/activesync.   

Both imap and activesync are enabled on my zoho account. 

Is there currently an issue for others?
