iphone 5 set up not working

Hi there - I have been trying to add my zoho email to my iphone 5 and it will not work!!!!  I added it to an iphone 6+ with no problem but it keeps telling me that the username/password is not recognized.  I've changed the password several times and still no luck.  Any help is appreciated!  I'm very frustrated right now!  Thanks
