Check Sync Email and Connected Account Settings

Verify if your external email address is properly configured as a connected account in Outlook.com.

An Outlook.com alias uses the same mailbox folders as your primary account and does not independently receive messages from other providers. To receive mail, the external address must be configured properly as a connected account.

1
Sign in to Outlook

Open your web browser and sign in to your Outlook.com account.

2
Open Settings

Click the Settings gear icon located in the top right corner of the page.

3
Navigate to Sync Email

Go to Mail, then select Sync email from the settings menu.

Check the list of connected accounts to see if your external email address is listed.

Frequently Asked Questions

Why doesn't my Outlook alias receive emails from another provider?

An alias only uses the same mailbox folders as your primary Outlook account. It does not actively import mail from an external mailbox unless the external address is configured as a connected account or via POP.

Why are my emails arriving slowly after setting up POP in Outlook?

A delivery delay is completely normal when an account is configured as a connected POP account. Outlook.com periodically checks and fetches mail from the external server, which can result in messages arriving slower than direct push email.

Can I add a new connected account to Outlook.com?

No. Microsoft discontinued the connected accounts feature in Outlook.com on May 10, 2021. If you already have a connected account set up, avoid removing it, as you will not be able to add it back.

How do I contact Outlook.com support for persistent email sync issues?

Sign in to Outlook.com using a web browser, click the Help (question-mark) icon, enter your question, scroll to the bottom of the help pane, and click 'Yes' under the 'Still need help?' prompt to reach the support team directly.
