Hello rdevoe99,
We’ve had numerous reports in the last days from AOL/Verizon/Yahoo users seeing “Incoming server login error” in Aqua Mail. It correlates with an issue on Yahoo/AOL’s IMAP side (rate‑limits/auth rejections). Their own app and some desktops keep working because they use a different API or a cached token, not standard IMAP.
Try the following:
Re‑add the account with OAuth2 Settings > Manage accounts > Add account > AOL/Verizon (or Yahoo) > Sign in. Complete the web sign‑in and grant access. This avoids password/app‑password issues and is what AOL/Yahoo prefer.
If you use manual setup: generate an app password in your AOL/Yahoo account security page and use it for both servers. IMAP: imap.aol.com, SSL/TLS, port 993 SMTP: smtp.aol.com, SSL/TLS, port 465 Username = full email address
If you still get errors after OAuth2 or an app password, it’s almost certainly the ongoing server issue. Keep using webmail/AOL app for urgent mail and try again later.
P.S. The issue should be resolved by AOL now.
