We open AOL Mail, enter our password, and the page returns an error message without a clear explanation. The usual reflex is to reset the password, but in many cases, the problem does not lie there. AOL Webmail login errors are often due to a server-side block, a misconfigured browser, or a conflict with a third-party email client.
AOL Security Block After Suspicious Login Attempts

The most confusing situation is when you are sure of your password and the login still fails. AOL applies temporary server-side blocks as soon as any activity is deemed suspicious: several consecutive unsuccessful attempts, logging in from a new country, or using a VPN.

In this specific case, resetting the password does not resolve anything. The account remains locked until the system automatically lifts the restriction. You can try to resolve AOL login errors by going through the account unlocking procedure, accessible from the AOL help page.
Feedback varies on this point, but the time to lift the block seems to range from a few hours to a full day. If you are using a VPN, disabling it before any attempt significantly reduces the risk of triggering the block.

- Turn off the VPN or proxy before logging in, then try again from the home network
- Avoid making more than two or three password attempts in a row: each additional failure extends the block
- Check if a recovery email or phone number is associated with the account; otherwise, the unlocking procedure will not succeed
AOL IMAP and SMTP Settings: Server Configuration Errors

When connecting your AOL mailbox to an email client like Outlook, Thunderbird, or Apple Mail, errors almost always stem from server settings. AOL imposes specific values and refuses the connection if even one field is incorrectly filled out.
Incoming IMAP Server Configuration
The incoming server must point to imap.aol.com, with port 993 and SSL/TLS encryption enabled. A common mistake is to leave the mail client’s default port (often 143), which results in an immediate refusal from the AOL server.
Outgoing SMTP Server Configuration
For sending, it’s smtp.aol.com on port 465 (SSL) or 587 (STARTTLS). SMTP authentication must be enabled with the same credentials as the AOL account. Without this option checked, emails will fail to send without an explicit message.
An additional trap concerns the application password. If two-step verification is enabled on the AOL account, the regular password will not work in a third-party client. You must generate a specific application password from the security settings of the AOL account and then use it instead of the usual password.
IMAP Migration to Google Workspace: “Request Expired” Error
This case affects users migrating their AOL mailbox to Google Workspace via the IMAP migration tool. Since the service update documented by Google, a “Request Expired” message regularly appears during authentication.
The problem arises from the approval mechanism: the holder of the AOL account must validate the connection within a limited time. If the approval does not arrive in time, the migration fails, and the error repeats with each new automatic attempt.
To work around the problem, manually initiate the migration and keep the AOL interface open in another tab to validate the request as soon as it appears. Automated and scheduled IMAP imports at night consistently fail if no one is there to approve.
Browser and Cache: The False Problems That Really Block
When connecting to AOL Mail via the browser displays a blank screen or an incomplete page, we rarely think of the cache. The cookies and data stored by the browser eventually conflict with the scripts on the AOL login page.
The most effective action remains to clear the cache and cookies related to the domain aol.com, then restart the browser. On Chrome, this option is accessed via Settings, then Privacy and security, then Clear browsing data.
- Test the connection in private browsing mode before touching the cache: if it works, the problem indeed comes from the stored data
- Temporarily disable browser extensions, especially ad blockers that interfere with AOL authentication scripts
- If multiple browsers are installed, reset the general web settings from the system options to avoid configuration conflicts between browsers
An outdated browser can also cause problems. AOL does not publish an official compatibility list, but versions of Chrome, Firefox, or Edge older than two years regularly cause display errors on the login page.
The good habit to adopt when using AOL Webmail regularly: keep your browser updated and clear the cache related to aol.com once a month. Most browser-related login errors disappear with these two actions, without having to touch the password or account settings.
