The partner sites offer access to tools and services that let you create a full-featured website solution, with special discounts available to Office 365 customers who come to their sites using links from Office 365.
Important: You must go to the partner sites using the links provided in Office 365. Sign in to your Office 365 account, and follow the steps here. The discounts are not available if you go directly to the partner websites.
The following website hosting companies currently partner with Office 365.
The partner-site offers are supported for most Office 365 customers and markets. If a website partner does not support the currency of your country or region, you'll be directed to the partner's US English website.
