Microsoft AppSource Certification Policies: Browser and Office Version Requirements for Excel Add-Ins

We're developing a cross-platform Excel add-in for financial reporting from Acumatica ERP and would like to publish it on Microsoft AppSource for our first trial customers.

 

During this test period, the add-in would be free of charge. Will the full scope of certification policies still apply to it? https://docs.microsoft.com/en-us/legal/marketplace/certification-policies

 

I am particularly concerned about this bit:

 

Your app or add-in must be fully functional with the supported operating systems, browsers, and devices for Office 2016, SharePoint 2013, and Office 365.

 

Your add-in will be tested and evaluated on Windows 10 (build 1903+ on Edge Legacy and earlier builds prior to 1903 with Internet Explorer 11).

 

  1. The wording is a bit ambiguous so it's not clear if we can target just the Office 365 and not support Office 2016, for example. Our core value proposition are JS custom functions, and those are not supported in one-time purchase versions of Office 2019 or earlier (https://docs.microsoft.com/en-us/office/dev/add-ins/excel/configure-your-add-in-to-use-a-shared-runtime). Please confirm that targeting only Office 365 is OK. Maybe policy wording could be amended to avoid confusion.
  2. We are concerned about the need to target IE11 and Edge Legacy. It would require some heavy polyfilling on our end; as such, we only targeted the latest Edge Chromium WebView. We planned to explicitly outline this requirement in the add-in description, but apparently we can't get through if we don't support IE11?

Do you have any plans to update the policy in that regard? It is a significant roadblock for us.
