3681747 - SAC Excel : Blank screen when connecting to SAC Tenant with SAC Excel add in

After executing successfully :

• In PowerShell, the command Set-OrganizationAddInOverrides -ProductId 8a512e2b-c04e-4c06-9235-11b6cd59f584 -AppDomains  "url1","url2"
  where the different tenants urls have to be declared between double quotes and separated by a comma without any space, and the URL tenant without the "/" at the end of the URL 
  (following the steps of "User guide about Tenant Configuration | SAP Help Portal" ("https://help.sap.com/docs/SAP_ANALYTICS_CLOUD_OFFICE/2b73edbc8f8f4189a36bc7a2e038185c/db2f874261824d63adb3ca198f65ce55.html"

• Clear the add-in cache in Excel clients, following the steps explained in User guide about Tenant Configuration. 

• To deploy, the administrator had installed Centrally the Excel Add-in but it has not been deployed after 72 hours 

==> When trying to login to the SAC tenant from SAC Excel Add-in, white/blank screen is always displaying :

• SAP Analytics Cloud - All versions
• SAP SAC Excel Add-in - All versions

Deploying the add-in centrally is the only way to choose : Loading the add-in directly from the add-in store from every user will definitely not work because the tenant configuration is only applied to the centrally deployed add-in. One prerequisite for central deployment is the usage of Exchange Online (see Documentation for Deploy and publish the add-in as administrator)

• From the documentation about Deploy and publish the add-in as administrator https://help.sap.com/docs/SAP_ANALYTICS_CLOUD_OFFICE/2b73edbc8f8f4189a36bc7a2e038185c/45ef30e1e14d4258864cbc794250289f.html?locale=en-US.
  One important step to focus : "Before you start, please check if your organization and users meet the requirements to use centralized deployment. The admin and the users must have Exchange Online and active Exchange Online mailboxes, for example."
• This is a requirement defined by Microsoft, see https://help.sap.com/docs/link-disclaimer?site=https%3A%2F%2Fdocs.microsoft.com%2Fen-us%2Foffice365%2Fadmin%2Fmanage%2Fcentralized-deployment-of-add-ins%3Fview%3Do365-worldwide.
• As long as you do not use Exchange Online, the central deployment of any Excel add-in will not work.
