NOTES:

  • Classic Outlook remains on the computer, even after a migration to Outlook (new).
  • Both Outlook classic and new can exist and run on a computer at the same time. There’s no conflict.
  • Outlook (classic) for Windows will remain supported until at least 2029.
  • Change to Outlook (new) when YOU are ready, not when Microsoft tries to force you.
