The great Yahoo Mail outage entered its third day on Thursday after hardware issues in one of Yahoo's data centers knocked out mail service for many users on Monday night. The Mail problems are ironed out for most people, but anyone who accesses their email with a third-party desktop or mobile app may still have issues.
In an update sent out late Wednesday, Yahoo said it has restored POP mail access for all affected users that access their mail using a third-party client. The company was still working on restoring IMAP service, which (like POP) allows you to retrieve mail with a third-party program. As of 11:00 a.m. ET, the company has not yet said whether IMAP was completely restored.
For anyone who uses IMAP to get at their Yahoo Mail, the company is advising users to access their mail through the Yahoo Mail app for Android or iOS, or on the web.
As of Wednesday night around 70 percent of messages sent during the outage had yet to be delivered to recipients. Yahoo says the remaining mail should be delivered by Thursday afternoon Pacific time. Some users may also be missing mail from their inbox dated between November 25 and December 9, Yahoo said earlier Wednesday. The company is currently working to restore any missing mail.
Yahoo's mail crash follows a major visual overhaul for the popular Webmail service in October. The new look was meant to modernize Yahoo Mail as it was beginning to look ancient compared to the continual improvements in Google's Gmail and Microsoft's Outlook.com.
Yahoo isn't the only company to experience a major mail outage in recent months. Microsoft's Outlook.com experienced outages in August and last March, and some Gmail users were hit with technical difficulties one year ago in December 2012.
Yahoo is providing periodic updates on Mail's status on its help page. The company hasn't said how many people are affected by the outage.
