We are developing a Word Web Add-In that will be used exclusively by our customers rather than the general public. Customers will need to log into the Add-In in order to use it with credentials we supply. My question is, is this Add-In ok to be distributed via the Office Store? Will it fall foul of the validation process if its functionality is not publicly available ? Obviously, we can supply credentials to the verification team at Microsoft in order to get the app published.
If this is a problem, how do ISVs distribute Web Add-Ins to customers external to their organisation (i.e. Without Sharepoint or Office Admin Centre)?
This model is supported via the Office Store - this blog post on add-ins which target organizations and enterprises rather than consumers may be of interest to you.
Please ensure that your add-in description clearly states the need for an additional account, as well as supplying test credentials for the validation team to use.
