Why my office 365 does not have ZOHO App?

Why my office 365 does not have ZOHO App?

I am trying to add the Zoho plugin onto my Microsoft outlook, but I cannot find Zoho Apps in 'All apps' in my office365 account Does that mean my office 365 must be a business account? Mine is 'Office 365 Home'.

I had a good Goole, but i couldn't see any subject is relevant.

Any help will be hugely appreciated.

Thanks

Sam
