Cost Management through Selective Deployment
By allowing administrators to exclude the new Outlook from installations where it is not needed, organizations can save on potential licensing costs associated with unnecessary app usage or support.
   - next-steps: Analyze user adoption and feature usage of Outlook across the organization to identify teams that may not require the new Outlook. Adjust licensing and deployment strategies based on these insights.
