Several users have flocked to X (formerly Twitter) to discuss this morning’s outage.
‘Been having trouble all morning, exchanging online, teams, prospects, none of these services are working as expected, also can’t get in to see quarantined emails. Your services are a joke right now,” one user tweeted.
Another added: “The prospects on a Monday morning must be some sick joke.”
And someone posted a GIF of a chimpanzee thrashing around its cage, writing, “What it feels like when the bane of my existence (Microsoft Outlook) won’t even open.”
Many users also joked that the outage of regular office software would give them at least a few minutes of free time this morning.

Microsoft has not yet commented on the cause of the outage or how long the disruption is expected to last.
However, reports of disruptions on Down Detector appear to have subsided from their previous peak.
As of 10:40 GMT, there were 647 reports of issues with Microsoft 365, up from 860 two hours earlier.
This latest outage comes just four months after Microsoft suffered an outage described as the “worst IT outage the world has ever seen.”
The outage affected supermarkets, banks, telecoms companies, streaming services and PCs, with airports, railways and GP practices also reporting problems.

It later emerged that the problems were caused by a glitch in the Crowdstrike cybersecurity service used by Microsoft.
The Microsoft outage was caused by a bug in the Crowdstrike software update, which was implemented in the ‘Falcon Sensor’, which searches for viruses and malicious attacks.
The resulting disruption left millions of passengers stranded at airports, while major airlines grounded their planes.
MailOnline has contacted Microsoft for comment.
