If you're currently experiencing a bit of trouble signing into any Microsoft services, you're not alone. Xbox, Outlook, and Skype appear to have all been hit with sign-in problems to some extent this morning, though the issue seems to be sporadic.
We've received tips that, in addition to the above, OneDrive appears to have been affected as well. In the case of Skype, Microsoft says it has resolved whatever was causing the problem. However, the Xbox Live Status Page shows it is still experiencing some issues, and the Outlook status shows much the same.
It's not clear what the cause of the issue is, but hopefully Microsoft is quick to resolving the outages. We'll update this article when things look in the clear.
Thanks for the tips, everyone!
