My Zoho email successfully syncs with the Outlook app on my iPhone. Yea!

I would like to have my Zoho calendar sync with the Outlook app on my iPhone, but cannot figure it out.

Also, all my contacts are currently on my iPhone in the native Contacts app. 

I would like to sync them with the Zoho contacts and then have them sync with the Outlook app on my iPhone.

Can you please help me.

Thank you,

Dean
