AOL IMAP Settings: Server, Port and SSL Setup Guide

Do not index

AOL IMAP settings are imap.aol.com on port 993 with SSL/TLS for incoming mail, and smtp.aol.com on port 465 with SSL/TLS, or 587 with STARTTLS, for outgoing mail. The username is the full AOL email address, and third-party clients may require an AOL-generated app password rather than the normal account password.

A working inbox doesn't prove that sending is configured correctly. Treat setup as separate checks for the server and encryption pair, login identity, and outgoing server, rather than retyping every field after each failure.

AOL IMAP and SMTP Settings at a Glance

The settings table applies to standard AOL addresses. Provider-managed or migrated addresses can use different outgoing servers, so the address type matters as much as the incoming hostname.

Each field has a specific job:

Server identifies the service the mail app connects to. Incoming and outgoing mail use separate services.

Port selects the connection endpoint. Enter the port in its own field, not after the hostname.

Encryption determines how the app establishes a protected connection. A correct port with the wrong encryption selection can still fail.

Username identifies the complete mailbox, including the domain after the @ symbol.

Password supplies the credential accepted by that connection method. An app password belongs in the ordinary password field.

Automatic configuration is convenient, but it isn't proof that every field is correct. Before saving, inspect the outgoing settings too, especially when the client fills them in without displaying a separate sign-in screen.

For legacy, regional, or provider-managed addresses, confirm current values in AOL's official help for that account type. The standard rule remains straightforward: encrypted incoming IMAP, authenticated outgoing SMTP, and the full address for both logins.

How to verify it: Run the mailX IMAP checker against the incoming configuration. A successful connection and encrypted session establish that the server settings work; successful authentication also confirms that AOL accepted the mailbox credentials.

Which AOL Port and Encryption Pairs Work and Common Mistakes

IMAP synchronizes server-side messages, folders, and mailbox state across devices. A message marked read or moved on a desktop should therefore show that change on the phone and in webmail.

Implicit TLS starts encryption immediately when the connection opens. STARTTLS begins with a protocol conversation and then upgrades the connection, so the two selections aren't interchangeable.

AOL's Verizon.net setup documentation specifies incoming imap.aol.com on 993 with SSL and outgoing smtp.verizon.net on 465 with SSL, demonstrating why an AOL incoming hostname doesn't establish the correct outgoing hostname.

Watch for these configuration mistakes:

STARTTLS selected for implicit-TLS IMAP: Run an IMAP connection test and inspect the encryption stage.

STARTTLS selected for implicit-TLS SMTP: Use the SMTP test to distinguish a handshake failure from a rejected login.

Unprotected incoming access: Restore the encrypted standard configuration rather than weakening security to get past an error.

Username missing its domain: An authenticated IMAP test can expose a rejected login, but it can't independently determine whether the username or password caused it.

App password missing: Successful encryption followed by rejected authentication warrants checking the credential type.

For additional port guidance, verify IMAP connection settings with mailX. Match the port to its encryption mode before changing credentials.

How to verify it: Run the IMAP checker for incoming settings and the SMTP test for outgoing settings. A failed encryption stage calls for correcting the connection mode before retrying login.

How to Set Up AOL Mail in Outlook, Apple Mail and Thunderbird

The setup screens differ, but each app needs the same three checks: the correct server and port pair, the full AOL email address as the login, and the right outgoing-server settings. Menu labels vary by operating system and app version, so use the closest equivalent account-management screen.

Outlook: manual setup steps

Open File, select Add Account, and enter the full AOL address.

If automatic setup fails, open Advanced options, enable manual configuration, and choose IMAP.

Enter the incoming and outgoing values from the settings table, with the matching encryption modes.

Complete AOL authorization if offered. If Outlook requests a password, use the credential required for the account.

Check the outgoing server's authentication fields before saving.

A Microsoft community support response about adding AOL Mail to Outlook recommends selecting IMAP through Advanced options. Manual setup also makes the server and port fields visible if automatic discovery fails or supplies unexpected settings.

Apple Mail: add the account

On macOS, open Mail, select Add Account, and choose Other Mail Account when manual entry is needed.

On an iPhone or iPad, open the Mail account settings, select Add Account, then choose Other.

Enter the display name, full AOL address, and required password.

Choose IMAP, enter both server hostnames, and set the matching secure connection options.

Save the account, then check the outgoing server's authentication fields.

Use the full AOL address in the username field. Apple Mail may display the name shown to recipients beside the login details, but the two fields serve different purposes.

Thunderbird: review automatic discovery

Open Account Settings, then Account Actions, and select Add Mail Account.

Enter the full AOL address and proceed to automatic discovery.

Select Manual configuration if discovery fails or supplies unexpected settings.

Choose IMAP, enter the incoming and outgoing configuration, and retain certificate validation.

Use OAuth2 if the account configuration offers it; otherwise, enter the required password.

After setup, compare the saved hostnames, ports, and encryption modes with the settings table. If an IMAP login still fails, mailX's IMAP checker can report whether the connection, encryption, and authentication succeed. It requires credentials for a mailbox you control, and credentials are not stored.

When AOL Requires an App Password

AOL webmail may accept the normal account password while a desktop mail app rejects it. That pattern can indicate that the third-party client needs an app password, not that the account password has been mistyped.

Use AOL's account-security controls to create the replacement credential:

Find the app-password controls and create a credential labeled for the app or device.

Copy the generated password exactly, checking AOL's current help for its expected format.

Paste it into both incoming and outgoing password fields when both services use password authentication.

Revoke that credential when the device or application no longer needs access.

A separate credential for each device makes revocation more manageable. Removing access for an old phone doesn't require replacing the credential used by a current desktop.

OAuth2 is preferable when the app offers a supported AOL authorization flow. It authorizes access through the provider's sign-in process instead of requiring the mail client to retain the normal account password.

AOL's account-security menus can change. Follow the current account interface rather than treating an old screenshot or menu path as authoritative.

How to verify it: Run the IMAP checker with the full address and new app password. Authentication should succeed; if encryption succeeds but login doesn't, check for a stale saved credential before generating another password.

Fixing AOL IMAP Connection and Login Errors

A timeout points to a different failure than a rejected login. Use the error stage to distinguish endpoint or network problems, encryption or certificate errors, credential and account-protection issues, folder-sync faults, and outgoing-server problems.

RFC 9051 requires IMAP implementations to support TLS 1.2 or newer and prohibits plaintext password mechanisms without an active protection layer. Keep encryption enabled; a login rejection calls for checking the credential and username, while a secure-connection error calls for checking the encryption mode and certificate.

A certificate warning needs its own investigation. Switching between STARTTLS and SSL/TLS can correct a mode mismatch, but it will not resolve an expired certificate, an incorrect hostname, or an untrusted certificate chain.

What belongs in a support request?

Include the application version, account type, failed connection stage, and redacted error text. Do not include passwords, app passwords, or API keys in support messages. If AOL IMAP failures occur alongside shared-drive disconnections on the same network, troubleshoot disconnected mapped drives to check for a broader network issue.

How to verify it: Run the IMAP checker after changing one setting. A successful connection, encryption, and authentication check confirms those stages are working. If the same stage still fails, focus on the setting or network condition tied to that failure.

Why AOL Receives Mail but Cannot Send

If AOL Mail can download messages but cannot send them, check the outgoing configuration separately. The incoming server can be correct while the SMTP hostname, port and encryption, or login details are wrong.

Work through these seven checks in order:

Confirm that incoming folders load normally.

Identify whether the mailbox is a standard AOL address or a provider-managed address.

Check that the outgoing hostname matches the account type.

Set the outgoing port and encryption pair for that hostname.

Enable outgoing authentication and enter the full mailbox address as the login.

Update the outgoing password explicitly if the app stores it separately.

Send a test message from a mailbox you control.

Change one outgoing setting at a time. If the connection fails, recheck the hostname and port-encryption pair. If the server rejects authentication, review the login address, saved password, and account requirements. A message accepted for submission can still fail to arrive, so check the sending app's result and the destination mailbox.

How to verify it: Use the mailX SMTP test with the outgoing endpoint and encryption mode you configured. A connection failure points to the endpoint or network path; rejected authentication points to the credentials or account policy.

How to Verify AOL IMAP and SMTP with mailX

Use the results to isolate which part of the AOL setup needs attention: the server and port pair, the login identity, or the outgoing server.

For incoming access, enter the full mailbox address and the configured IMAP details in the IMAP connection test. Its connection, encryption, and authentication results help distinguish a server or port mismatch from a login problem.

Test outgoing access separately with the mailX SMTP test, using the outgoing server and its matching encryption mode. If the endpoint is uncertain, the IMAP finder returns standard AOL Mail settings, including imap.aol.com on port 993. The finder provides settings without logging in.

What permission does a login test require?

SMTP and IMAP login tests are for accounts the user controls and require an explicit request and credentials supplied for that test. The password is used to run the test, is not stored, and is redacted before the request is saved.

Use a dedicated app password when appropriate, and revoke it afterward if it was created solely for diagnostics. An agent must get confirmation before running a credential-based test. An SMTP test can send a test email.

How to verify it: Rerun only the test for the stage you changed, then check whether that result passes.

Confirm the Working Settings Before You Sync Devices

Record the working configuration before applying it to other devices. This makes it easier to identify whether a later problem comes from the server settings, the login identity, or the sending configuration.

Save the hostnames, ports, encryption modes, and username format that work.

Keep a note of whether incoming and outgoing connections both pass.

Enter the settings on each device, using separately revocable app passwords where needed.

Send a controlled message from each device and check that it arrives and appears in the Sent folder.

After account-security changes, check whether saved credentials still work before changing server settings.

If you need to confirm the incoming server details, check IMAP settings before editing a configuration that already works. Once the settings are recorded, sync devices one at a time. A failure limited to one device points to its saved credentials or local configuration, rather than a reason to change every device's settings.

Frequently Asked AOL IMAP Questions

Should AOL use POP3 or IMAP?

IMAP is the practical choice for a mailbox accessed from several devices because it synchronizes messages and folders with the server. POP3 typically downloads messages and may remove server copies, depending on the client's settings. Local offline access isn't exclusive to POP3, since IMAP clients can cache mail too. Confirm AOL's current POP3 configuration before choosing it.

Do the same AOL settings work on phones?

Phone mail apps use the same server, port, and encryption combinations as desktop clients. The menus differ, and some apps offer an AOL authorization flow instead of manual password entry. A password-based setup may require an app password. Confirm the account type and inspect outgoing authentication even when incoming mail starts syncing immediately.

Must settings change after an AOL password change?

A password change doesn't normally require different server hostnames or encryption modes. Saved credentials may need updating, and app-password behavior should be checked in AOL's current account-security guidance. If access fails, replace or regenerate the affected credential as appropriate, update incoming and outgoing authentication, and rerun the IMAP checker before changing unrelated settings.
