On Wednesday morning, Outlook and several other 365 services were down. Could the outage – which affected thousands of users – be caused by a failed internal update?
During the morning, thousands of Microsoft users worldwide reported that they have problems with e.g. the email service Outlook, Teams and the cloud service Azure.
Big problems with Teams
Microsoft confirmed that it had problems with several of its 365 services. Among other things, disruptions made it difficult for users to connect to video meetings, as well as receive and send messages. Information was also circulated that cloud services connected to Azure, such as SQL Server and Web Apps, were affected.
We’re investigating issues impacting multiple Microsoft 365 services. More info can be found in the admin center under MO502273.

During the morning, Microsoft referred to a case number in their tweet where they told about the disruptions. But many pointed out in the Twitter thread that it was difficult to follow the matter via Microsoft’s site because it was down at the time.

Many Swedes affected
Microsoft has not yet released information on how many users were affected by the disruption. Teams alone is estimated to have more than 280 million users globally.
Data from the Downdetector service showed more than 3,900 reported incidents in India, and over 900 in Japan as of Wednesday morning. In Sweden, the number of reported errors soared around 9 a.m. on Wednesday, with 289 incidents, according to Downdector. Just before 11 o’clock the number of reported cases among Swedish users had dropped drastically.
In a tweet published this morning, Microsoft writes that it was likely a network update that caused the disruption. The update has now been rolled back, according to the tech giant.
We’ve rolled back a network change that we believe is causing impact. We’re monitoring the service as the rollback takes effect.
