In order to make room for new improvements and provide the best user experience, Slack will occasionally retire a feature from the product. We'll always do our best to provide advanced notice and recommend alternatives to admins and affected members before saying a final farewell to any feature.
The MSI for per-user deployment and the MSI for machine-wide installation will be replaced with the the MSIX installer. Your IT team will need to uninstall the MSI package and deploy Slack using the MSIX for Windows.
