THIS MIGHT AFFECT YOU - it's a wide-spread outage:
AOL-Verizon email NOT working with Outlook. This is on two separate computers and two separate email accounts. However, AOL-Verizon Webmail works on Chrome browser. Email also coming through on Android and Apple iPhones two different email accounts, on Verizon Wireless. This is in PA. Outlook email is the issue. If this affects you, continally check send/receive on your PC.
If not resolved by tomorrow, call AOL
customer support.

Thank you Elena. This is good to know.

Seems like a global problem.

The email send/receive problem has been resolved (for me).
