Steps

  1. Open Outlook on your computer.
  2. Click File in the top left corner.
  3. Click Account Settings, then Account Settings again.
  4. On the Email tab, click New.
  5. Enter the email address and click Connect (or Next).
  6. Enter the password when asked and complete any sign-in prompts, such as MFA.
  7. When you see a success message, click Done (or Finish).
  8. Close the Account Settings window. The new account appears in the left folder list.

Good to know

  • If the account is a shared mailbox and you have not been given access, the sign-in will fail. Open a ticket to request access.
