Microsoft’s Office 365 has been giving some users cold sweats. No matter how hard they try to log in, they simply can’t access the service and haven’t been able to for hours – others say it has wobbled for days.

Sporadic reports of unrest began to emerge on Down Detector on Friday (26 October) in the UK and across the pond, stopped over the weekend and started again prior to 0800 GMT today. Office 365’s web woes have still not been resolved at the time of writing.

The first complaint was spotted on Twitter just after 0700 GMT.

Microsoft, at least initially, seemed to know nothing of the activation worries to which admin Tom Ruben referred, but he was backed up by others.

Admins raised support tickets with Microsoft but complained they’d only received acknowledgement of the outage early on in the screw-up and had precious else since.

Microsoft has said it is “investigating issues related to repeated credential prompts and users being unable to log in using the Outlook client under EX152471”. It asked admins to “please check the admin centre for more details”.
