AOL.com is a consumer webmail service now operated by Yahoo Inc. (owned by Apollo Global Management since 2021). Standard IMAP, POP3, and SMTP with SSL/TLS are supported for third-party mail clients (Outlook, Thunderbird, Apple Mail, mobile). Since 2019, AOL requires an app-specific password rather than the account password for any third-party client access.
AOL rejects your account password when connecting from Outlook, Thunderbird, or any third-party mail client. Generate an app-specific password from AOL account security settings (Account Info, Manage account security, Generate app password) and paste the 16-character string into the mail client’s password field. Use a distinct app password per client so revoking one does not lock out the others. Reference: SMTP 550 5.7.1 guide.
Quick Reference: AOL.com Server Settings
Configure the mail client with the values below. The password field takes the AOL app-specific password, not the AOL account password.
| Protocol | Server | Port | Encryption | Authentication |
|---|---|---|---|---|
| SMTP (outgoing) | smtp.aol.com | 465 (SSL) or 587 (STARTTLS) | Required | Full email + app password |
| IMAP (incoming, recommended) | imap.aol.com | 993 | SSL/TLS | Full email + app password |
| POP3 (incoming, single device) | pop.aol.com | 995 | SSL/TLS | Full email + app password |
AOL.com SMTP Settings (Sending Mail)
SMTP handles outbound mail. Use smtp.aol.com on port 465 with SSL/TLS or 587 with STARTTLS. Username is the full user@aol.com address; password is the app-specific 16-character string generated for this client.
If the mail client returns an authentication error, verify two things before regenerating the password: first, that the username is the full email address (not just the local part); second, that the app password was not truncated on paste (Outlook sometimes strips spaces). AOL enforces per-account daily send limits to prevent abuse; consumer accounts typically top out at a few hundred outbound messages per day.
AOL.com IMAP Settings (Recommended for Reading)
IMAP synchronizes message state across all configured devices. Use imap.aol.com on port 993 with SSL/TLS. Same app-specific password as SMTP.
Server-side folder mapping follows the standard AOL scheme (Inbox, Sent, Drafts, Spam, Trash). Custom folders you create in AOL webmail also sync to IMAP; older Thunderbird versions may require explicit folder subscription to see them.
AOL.com POP3 Settings (Single-Device Access)
POP3 downloads mail to a single device. Use pop.aol.com on port 995 with SSL/TLS. Same app-specific password as SMTP and IMAP.
Enable “Leave messages on server” in the client’s POP3 advanced settings if you want mail preserved for AOL webmail access or other devices. Otherwise mail retrieved on device A is removed from the server and unreachable from device B or from webmail.

About AOL Mail
aol.comaim.com · love.com · ygm.comAOL Mail traces its origins to America Online's consumer service launched in 1991, with public email available by 1993. During the mid-1990s and early 2000s, AOL was the dominant American internet gateway, with an estimated 27 million subscribers at its 2002 peak. The "You've got mail" audio notification became a cultural touchstone.
AOL's corporate history includes the infamous 2000 merger with Time Warner (widely considered one of the worst mergers in business history), followed by a 2015 acquisition by Verizon for .4 billion, and finally a 2021 sale to Apollo Global Management as part of the Yahoo transaction. AOL Mail now operates on the same infrastructure as Yahoo Mail.
Free AOL Mail accounts remain available with unlimited storage. The service is used primarily by legacy users maintaining decades-old @aol.com addresses; new signups are minimal. AOL Mail uses standard IMAP, POP3, and SMTP protocols, sharing endpoints with Yahoo Mail since the infrastructure merger.
Timeline
- 1993AOL Mail available to consumers
- 2000Merger with Time Warner (5B, later written down)
- 2002Peak of ~27 million subscribers
- 2006AOL Mail becomes free (previously subscription-tied)
- 2015Acquired by Verizon for .4B
- 2021Sold to Apollo Global Management (with Yahoo)
The "You've got mail" voice was recorded by Elwood Edwards in 1989 and remained AOL's email notification for decades. AOL Mail also operates the AIM.com domain (from AOL Instant Messenger, discontinued 2017). Long-standing @aol.com addresses often carry more legacy trust weight than newer addresses in age-of-account signals used by some receiving systems.
Frequently Asked Questions
How do I generate an AOL app password?
Log into your AOL account at login.aol.com, click your profile, go to Account Info, then Account Security, then “Generate app password.” Name the password (e.g., “Thunderbird laptop”), copy the resulting 16-character string, and paste it into the mail client’s password field. Use one app password per client rather than sharing a single string.
Why does AOL reject my regular account password?
Since 2019 AOL requires app-specific passwords for third-party mail client access. This is a security measure to reduce the impact of a compromised account password: the app password is scoped to mail client access only and can be revoked without changing the main account password.
Does AOL support OAuth2?
AOL supports OAuth2 in the AOL Mail app and select Yahoo-owned clients but not through the smtp.aol.com / imap.aol.com endpoints exposed to third-party clients. For Outlook, Thunderbird, and Apple Mail, use the app-specific password mechanism above.
Can I add AOL.com to Gmail as a secondary mailbox?
Yes. In Gmail: Settings, Accounts and Import, Add a mail account. Configure POP3 pull with pop.aol.com on port 995 SSL/TLS using your AOL email address and an AOL app-specific password. Gmail then pulls AOL mail into your primary Gmail inbox on a schedule.
Which SMTP port works when 587 is blocked?
Switch to port 465 with implicit SSL/TLS. Corporate networks and some mobile carriers block outbound 587 but leave 465 accessible. Both ports use the same AOL app-password authentication.
About This Guide
The AOL.com server settings on this page were last verified in July 2026 against AOL customer support documentation and the current Yahoo Inc. postmaster guidance. The app-password requirement has been stable since 2019 and applies to all third-party client access. SMTPedia re-verifies these settings quarterly. If you find a discrepancy between what is documented here and what AOL currently requires, please report it so we can update the reference.
