Yahoo Mail and AOL's email service appeared to have crashed on Thursday.

Users reported a "temporary Error: 15" message that kept them from accessing their email through Yahoo or AOL, which are part of the same overall company.

Down Detector showed spikes in user-reported issues starting in the mid-morning for both Yahoo and AOL. Those reports appeared to be going down Thursday afternoon, though it is not clear if the issues are resolved. (Disclosure: Down Detector is owned by Ziff Davis, the same parent company as Mashable.)

Both Yahoo and AOL acknowledged there appeared to be a problem via identical posts on X.

"We understand some users are currently experiencing difficulties accessing their accounts," the posts read. "We are actively investigating this issue and will provide updates as soon as more information becomes available. We appreciate your patience and apologize for any inconvenience this may cause."

Users online both complained about the email services being down and made jokes about folks still using AOL or Yahoo as their email provider in 2025.
