Transferring Calandar from Outlook Classic to New Outlook?

You can transfer your calendar from Outlook Classic to New Outlook by syncing your account. Just sign in to the same Microsoft account in the new Outlook, and your calendar will automatically appear if it’s cloud-based (Exchange or Outlook.com). If your calendar is saved locally in a PST file, you may need to import it first in Classic Outlook and then sync it to the account. Microsoft has designed the new Outlook to automatically sync mail, contacts, and calendar once the account is added, so manual transfer is usually not needed unless data is stored offline.
