Known Error impacting Outgoing Penn State Emails

As of 6 p.m., Wednesday, Dec. 13, AOL and Verizon began rejecting email sent by one of Penn State’s outgoing email servers.
Clients such as Outlook, Hotmail, Thunderbird, Apple Mail, Android Mail, and iOS Mail may have trouble sending email to
addresses that end with AOL.com or Verizon.net. Penn State IT staff members are currently monitoring the issue, and more
information will be shared as information becomes available. We expect this issue to be resolved later tonight.
