Yahoo's email service was struggling Thursday, and users around the globe were complaining that they hadn't had access for most of the day.

It's not yet clear when the service started to stagger or how many of Yahoo's users have been affected. However, Yahoo confirmed via Twitter that there is a problem.

"We are aware that we have experienced an outage, and we are working to address the issue," Yahoo tweeted on its @Yahoo account. "We appreciate your patience."

While some users seemed fairly patient about the inconvenience, others sounded a bit more frustrated when they took to Twitter to vent about the outage of their free email service.
