First, let’s open Outlook. Click the Windows Start button, type Outlook, and then launch the Outlook App.

Once Outlook is open, go to the upper-left corner and click the File tab. On the Info screen, you will see a large button labeled + Add Account. Click this now.
In the new window, enter your full Microsoft 365 business email address. For example, name@yourcompany.com.

After entering your email, click Connect. Outlook will now automatically start the process of finding and setting up your Exchange server settings.


You will be presented with a Microsoft sign-in prompt.
Enter your Microsoft 365 password and click Sign in.

If your organization uses Multi-Factor Authentication, or MFA, you will be prompted to verify your identity. Follow the on-screen instructions, which may involve approving the sign-in from your phone or using an authentication code.
