Reports of disruption on Down Detector do appear to be coming down after their earlier peak.
As of 10:40 GMT, there were 647 reports of issues with Microsoft 365 – down from 860 two hours earlier.
This latest outage comes just four months after Microsoft suffered an outage described as the ‘most serious IT outage the world has ever seen’,
Commenter took to X to vent as the issue left them unable to access emails or calendar information
The outage hit supermarkets, banks, telecoms, streaming services and PCs, with airports, railways and GP surgeries also among those reporting problems.
It later emerged that the issues had been caused by a glitch in the Crowdstrike cybersecurity service which is used by Microsoft.
The Microsoft outage was triggered by a bug in Crowdstrike’s software update, which was deployed to its ‘Falcon Sensor,’ which searches for viruses and malicious attacks.
The resulting disruption left millions of passengers stranded at airports as major airlines grounded planes.
MailOnline has contacted Microsoft for comment.
