Quick answer: If AOL Mail was working in Outlook and suddenly stopped, authentication is the first thing to check — Outlook may need to be reauthenticated, or a saved app password may no longer be accepted. Other causes include incorrect account settings, an outdated Outlook version, an Outlook profile issue, or a temporary AOL service problem. Start by confirming AOL Mail works in a browser, then reauthenticate the account in Outlook before removing and re-adding it.

Why Is AOL Mail Not Working with Outlook?
A handful of things typically break an existing AOL-Outlook connection:
- Authentication needs to be refreshed. Outlook’s saved credentials — whether your AOL password or an app password — can stop being accepted even without anything changing on your end, and reauthenticating usually resolves it.
- App password needs to be regenerated. App passwords don’t expire on their own, but they stop working if deleted, revoked, or if 2-Step Verification was turned off after the password was created.
- AOL’s temporary service issue. AOL occasionally has short outages that affect mail delivery or authentication.
- Outlook update or profile corruption. A Windows or Outlook update can sometimes disrupt an existing account connection.
- Security software interference. Antivirus programs with email-scanning features can occasionally block IMAP/SMTP traffic, though this is less common than an authentication issue.
- AOL account security flag. Unusual sign-in activity can cause AOL to require re-verification before allowing app access.
Note: AOL has not discontinued Outlook support and continues to support standard IMAP/SMTP connections for third-party mail clients, alongside app passwords for clients that don’t support AOL’s secure sign-in. If you see a persistent failure, it’s almost always one of the causes above rather than AOL dropping compatibility.
Fix It Fast: Quick Troubleshooting Checklist
Before diving into individual fixes, run through this in order — it’s the fastest path to resolving most authentication-related failures:
- Confirm AOL Mail works in a browser at mail.aol.com
- Reauthenticate: remove and re-enter your password (or app password) in Outlook
- If that doesn’t work, generate a new AOL app password and use that instead
- Remove and re-add the AOL account in Outlook as a last resort
- Confirm Outlook is updated to the latest version
If steps 2–3 don’t fix it, work through the detailed steps below.
Step-by-Step Fixes
1. Check whether AOL Mail works in a browser
Log in at mail.aol.com. If your account won’t load or shows an error there, the problem is on AOL’s side (account lock, outage, or security flag) — not an Outlook configuration issue. Fix the account access problem first before troubleshooting Outlook. If webmail works, your AOL account is accessible through the browser, so the problem is more likely related to Outlook’s authentication, configuration, or connection to AOL.
2. Reauthenticate your AOL account in Outlook
AOL recommends reauthenticating a third-party mail application when access stops working. In Outlook, go to File > Account Settings > Account Settings, double-click the AOL account, and remove and re-enter the password (or app password) currently being used. If you’re using an app password and re-entering it doesn’t resolve the issue, generate a new one and try again.
3. Generate a new AOL app password if reauthentication doesn’t work
If simply re-entering the existing password doesn’t fix it, the app password itself may have been deleted or revoked. Go to Account Info > Account Security in AOL and follow the prompts to generate an app password. If the option isn’t available on your account, check AOL’s current account-security requirements before proceeding. AOL won’t show you the password again after you leave that screen, so copy it immediately, then enter it in Outlook in place of the old one.
Don’t keep re-submitting your regular AOL account password if Outlook is rejecting it and prompting for an app password — for clients that require one, only a freshly generated app password will work.
4. Remove and re-add the AOL account in Outlook
If reauthentication and a new app password both fail, remove the account entirely and set it up again. If your account is configured as POP3 rather than IMAP, back up your Outlook data file (.pst) first — POP3 stores mail locally on your device, and removing or reconfiguring the account can affect access to that locally stored mail. IMAP accounts don’t have this risk, since mail stays on AOL’s server.
Go to File > Account Settings > Account Settings, select the AOL account, remove it, then re-add it manually using IMAP with your current app password. A clean re-add clears out any corrupted authentication tokens that reauthentication alone doesn’t fix.
5. Check Outlook’s send/receive settings
If mail is arriving but not sending (or vice versa), check Send/Receive Groups to confirm the account is included and that “Include this group in send/receive” is checked. A disabled send/receive group looks identical to a broken connection but isn’t an authentication problem.
6. Update Outlook
Older Outlook builds can lose compatibility with current authentication requirements. Go to File > Office Account > Update Options > Update Now.
7. Repair or recreate the Outlook profile
If the account still won’t connect after a clean re-add, the Outlook profile itself may be the issue. Create a new Outlook profile (Control Panel > Mail > Show Profiles > Add) and add the AOL account there.
8. Check for a temporary AOL outage
If none of the above works and mail.aol.com is also behaving oddly, the issue may be a temporary problem on AOL’s end rather than anything in Outlook. Wait and retry.
As an additional troubleshooting step if the connection still fails with no clear cause: antivirus software with email-scanning features can occasionally intercept IMAP/SMTP traffic silently. Temporarily disabling email scanning to test is worth trying, then re-enabling it once you’ve confirmed whether it’s the cause.
AOL Mail Isn’t Sending or Receiving in Outlook
If the connection works but only one direction is failing, narrow it down further:
If you can receive but can’t send:
- Confirm SMTP authentication is enabled in Outlook’s account settings
- On Verizon.net accounts, double-check the SMTP server is smtp.verizon.net, not smtp.aol.com
- Test sending a message from AOL webmail to confirm the account itself can send
If you can send but can’t receive:
- Check that IMAP settings match what’s in your AOL settings guide
- Check Outlook’s Send/Receive Groups to confirm the account is included
- Check whether new mail is arriving in AOL webmail but not syncing to Outlook — this usually points to a folder sync or IMAP subscription issue rather than authentication
AOL Works in a Browser But Not in Outlook — What That Means
This is one of the most common variations of the problem. If AOL Mail works fine at mail.aol.com, your AOL account is accessible through the browser, so the problem is more likely related to Outlook’s authentication, configuration, or connection rather than your AOL account itself.
In this situation, skip account-recovery steps entirely and go straight to reauthenticating or generating a new app password and re-adding the account in Outlook (steps 2–4 above).
Check Your AOL Mail Settings
Incorrect IMAP or SMTP settings can also prevent Outlook from sending or receiving AOL Mail, though this is less common on an account that was previously working. Rather than duplicating the full configuration here, check the current server settings, ports, and encryption details in our AOL Mail settings for Outlook guide and confirm they match what’s saved in Outlook.
Verizon.net users: your incoming (IMAP) server is the same as standard AOL.com accounts, but your outgoing (SMTP) server is different — smtp.verizon.net rather than smtp.aol.com. Using the standard AOL.com SMTP server on a Verizon.net address is a common cause of “mail receives but won’t send” on these accounts specifically.
Does Outlook Still Support AOL Mail on Every Version?
Yes — AOL Mail can be used with Outlook 365, Outlook 2021, Outlook 2016, and Outlook 2010 through supported third-party IMAP/SMTP or app-password connections. Older versions like Outlook 2010 may have additional compatibility or security-protocol limitations, so if you’re troubleshooting on an older version and nothing above resolves it, updating to a current Outlook version is often the more reliable fix than continued troubleshooting.
Still Can’t Get AOL Mail Working?
If you’ve completed the steps above and AOL Mail still doesn’t work in Outlook, test the account in webmail again and check your AOL account’s recent sign-in activity for security alerts. If webmail works but Outlook doesn’t, create a new Outlook profile and reconnect the account. If the problem affects both Outlook and AOL webmail, the issue is more likely account- or service-related than an Outlook configuration problem.
Frequently Asked Questions
Why does Outlook keep asking for my AOL password? This usually means Outlook is trying to authenticate with your regular AOL password instead of an app password, or the app password it has saved was revoked or expired. Generate a new app password and re-enter it.
What is the IMAP password for AOL Mail? If Outlook is rejecting your regular AOL password, generate an app-specific password under Account Security in AOL and use it for both IMAP and SMTP authentication instead. Whether an app password is required depends on your account’s security settings and which sign-in method Outlook is using.
Why is AOL Mail not working today? Check mail.aol.com directly. If it won’t load or shows errors, the issue is with AOL’s service rather than your Outlook setup. If AOL loads fine, the problem is isolated to your Outlook connection — see the fixes above.
Can I use my AOL email in the Outlook app? Yes. AOL Mail can be used with supported Outlook applications, but the exact sign-in process can vary by Outlook version and platform. For Outlook Desktop specifically, AOL currently recommends using a third-party app password when secure AOL sign-in isn’t supported.
Does Outlook still support AOL Mail? Yes. AOL Mail can be used with supported versions of Outlook through third-party mail protocols. The authentication method depends on the Outlook version and your AOL account’s security configuration.
Conclusion
Most cases of AOL Mail not working with Outlook come down to an authentication problem, such as a password that needs to be re-entered, an app password that has been deleted or is no longer accepted, or an account that needs to be reauthenticated. Confirm your AOL account works in a browser, reauthenticate in Outlook, and generate a new app password if needed — that sequence resolves most of these issues.
If you’re troubleshooting AOL Mail because you’re considering moving your mailbox to another platform rather than continuing to maintain the Outlook connection, you don’t have to rely on Outlook as your migration method. SkyMigrate’s IMAP Backup Tool can back up or migrate AOL mailboxes directly.
