While some Outlook users complained that they were greeted with an error page, others said they were taken to a blank page or received a message claiming their account does not exist. The issue was first reported at around 12:00 GMT (7am ET). A similar problem was also reported by Skype users who were having trouble logging on the chat and video calling service. Also, many Xbox players couldn’t access their Xbox Live accounts. Both these services are run by Microsoft. The problem appears to be affecting those with Microsoft accounts across the world. However, problems with these services aren’t as widespread. Issues have been reported throughout Europe and the U.S. Frustrated users took to Twitter to complain about not being able to log in to their email accounts at Hotmail and Outlook. ‘Microsoft Outlook has stopped working. Does not recognise my email address and/or just takes me to an error page. What’s going on?’ wrote Twitter user Gareth Bell. ‘It’s asking me to re-enter my password and then telling me my email doesn’t exist. I’ve had this email address over 10 yrs!’ wrote Linzi Horn on the Down Detector website. User Georgia Hall tweeted: ‘Your servers are down…please address this as a whole, not each one as individual problems! Hope to get his fixed asap!’ However, one user said on Twitter that Microsoft said it is working on resolving the issue. “Sorry for the inconvenience. We know about the issue and are currently working on the resolution. Request you try and login again after a few hours,” the firm said, albeit vaguely. Microsoft has not yet commented on the massive outage its services are facing. In the meantime, the @MicrosoftHelps Twitter support account is currently being flooded with requests from users who are having difficulties with Microsoft accounts.
