If you would like to deploy an add-in to a tenant, the Best solution is through Centralized Deployment manage-deployment-of-add-ins
The tenant admin could deploy the add-in, it doesn't need installation by single users.
We created an Excel Web Add-in to replace an XLSM that we’ve been distributing for nearly 20 years.
How can we deploy an Excel Web Add-in to 100’s of existing single tenant web sites that are either on-premise or cloud hosted?
None of these standard Manifest Deployment Options seem to work for us:
• Network Share – non-production and no mac support / version checking.
• AppSource – since the web add-in needs to talk to the user’s app server, the add-in has to be installed on each user’s application server. Is this 100+ apps?
• Microsoft 365 Admin Center – still AppSource. Right?
• SharePoint Catalog – no support for Mac and requires centralized SharePoint use.
Am I missing something?
Why not a capability like WEB DEPLOY (with version checking)?
