Generate and Use an AOL App Password via IMAP

AOL requires a secure, one-time app password for third-party email clients like Outlook instead of your standard account password.

Because of enhanced security protocols, entering your standard AOL password directly into Outlook will result in persistent authentication failures. You must generate a specialized App Password from AOL's account security settings and use it alongside manual IMAP configuration in Outlook.

1
Generate the AOL App Password

Go to the AOL webmail site, log into your account, navigate to 'Account Security', and select 'Manage app passwords'. Generate a new password specifically for 'Outlook Desktop' and copy it to your clipboard.

2
Start Manual Setup in Outlook

Open Outlook, go to File > Add Account. Enter your AOL email address, click 'Advanced options', check the box for 'Let me set up my account manually', and click Connect.

3
Select IMAP Account Type

On the 'Choose account type' screen, click the 'IMAP' icon to configure the AOL server settings manually.

4
Enter the App Password

When Outlook prompts you for a password, paste the 16-character App Password you generated from AOL (do not use your regular password) and click Connect.

5
Verify Server Settings

If prompted for server details, ensure the incoming mail server is set to imap.aol.com (Port 993, SSL/TLS) and the outgoing mail server is smtp.aol.com (Port 465, SSL/TLS).

Generate and Use an AOL App Password via IMAP
Setup Complete: Once connected, Outlook will begin downloading your AOL emails. You will not need to enter this app password again unless you set up the account on a new device or software.

Frequently Asked Questions

Why is Outlook suddenly not accepting my AOL password?

AOL updated its security standards to block standard passwords on third-party email apps. You must now use a dedicated, system-generated App Password from your AOL account security settings to log in via Outlook.

What should I do if the AOL app password still doesn't work?

Ensure you are selecting 'IMAP' instead of 'POP' or 'Exchange' during manual setup. Verify that the app password was typed correctly without spaces. If the issue persists, delete the app password in AOL, generate a new one, and try again.

What are the exact IMAP server settings for AOL Mail?

For IMAP, the incoming server is imap.aol.com using Port 993 with SSL/TLS encryption. The outgoing server (SMTP) is smtp.aol.com using Port 465 with SSL/TLS encryption.
