Starting last September Microsoft starting pushing out Outlook (new) on all Windows 11 devices. This app is different from the Outlook 2019 app that is provided by Mitchell OIT.
We recommend using the Outlook 2019 that is per-installed on all Mitchell Machines.
Using the new Outlook app may not work and is recommended you stay with using the Desktop 2019 or Outlook web app.
