Unknown software problem caused the outage, which was resolved five hours later
An unknown software problem earlier today left AOL LLC’s 27 million paid members worldwide unable to send or receive e-mails reliably for about five hours, according to the Dulles, Va.-based company.
"Late this morning, an e-mail software issue started to cause delays in the sending and receiving of AOL e-mails for our members and AOL.com users," AOL spokesman Nicholas Graham said in a statement.
The problem was fixed about 4 p.m. and all accumulated e-mails are being delivered, Graham said.
