If you're hitting a snag trying to use any number of Microsoft services today, you're not alone. Along with a Xbox Live outage, it appears that signing into OneDrive, Outlook and other Microsoft services is down for at least some users.
For its part, Microsoft has acknowledged the Xbox Live outage on its service status page, noting problems with everything from signing into your account to buying games. As for the other services, a number of users are reporting issues on Twitter, and a quick look at Down Detector shows Outlook, Skype, OneDrive, and Office 365 are all affected to some extent.
Hopefully whatever is wrong gets cleared up quickly. We'll update this post with more once things are in the clear.
