We're just making sure you're all aware of Outlook.com issues Microsoft is currently working hard to address. The service is currently experiencing technical problems that may affect not only those rocking Windows 8.1, but also Windows Phone owners.
According to Microsoft's service bulletin:
"We are aware that users of the following mail clients are experiencing issues syncing and sending email. We are working on the issue and expect resolution in the next 24 hours. - Windows Live Mail - Outlook Connector - MSN Premium client. - Windows Phone 8.1 - Windows 8 Mail Client "
The company has since updated the notice, apologizing for the lengthy disruption of service, which appears to be taking longer than expected to fix. Hopefully everything will be resolved soon.
Thanks, Koen, for the heads up!
