How to Add an Additional Email Account to Outlook (Windows)

Overview

You can add multiple email accounts to the Outlook desktop app on Windows. This allows you to manage a shared mailbox, distribution group inbox, or a second personal account from within the same Outlook client.

Steps to Add an Account

1. Open Outlook on your Windows PC.
2. Click the File tab in the top-left corner of the ribbon.
3. Select Add Account.
4. Enter the email address you want to add and click Connect.
5. Enter the password when prompted, then click Sign In or Next.
6. If required, complete any additional authentication (e.g., Microsoft Authenticator approval or Duo 2FA).
7. Click Done. The account will appear in the left-hand folder pane in Outlook.

Adding a Shared Mailbox

Shared mailboxes are typically added automatically if your IT admin has granted you access. If it does not appear within 24 hours:

1. Go to File → Account Settings → Account Settings.
2. Select your primary account and click Change.
3. Click More Settings → Advanced → Add.
4. Type the shared mailbox address and click OK → Next → Finish.

Troubleshooting

• Authentication loop? Sign out of all Microsoft accounts in Windows Settings and retry.
• Account not syncing? Check your internet connection, then try removing and re-adding the account.
