According to data from DownDetector, issues began at roughly 7am GMT/11pm ET, preventing users from logging in and causing a big spike in complaints.
The outage appears to be part of a wider issue affecting the entire Microsoft 365 platform, with Outlook users also reporting issues.
Good morning – if you’re just logging on for work and having problems with Microsoft 365 – you aren’t alone.
The platform is seeing widespread issues, with users across Europe and Asia unable to access a number of services, including Microsoft Teams and Outlook.
The good news is that Microsoft does appear to have noted the problem, so a fix may not be too far off.
“We’re investigating issues impacting multiple Microsoft 365 services. More info can be found in the admin center under MO502273,” the Microsoft 365 Status twitter account said.
More information from Microsoft – seems it has found the cause of the problem, but things aren’t fixed just yet.
We’ve identified a potential networking issue and are reviewing telemetry to determine the next troubleshooting steps. You can find additional information on our status page at https://t.co/pZt32fOafR or on SHD under MO502273.January 25, 2023
As that tweet mentioned, users can see more information on the official Microsoft 365 “Service Health Status” page.
It doesn’t make for particularly good reading right now though…
“Users may be unable to access multiple Microsoft 365 services,” the alert reads, noting that the following services are affected:
Microsoft TeamsExchange OnlineOutlookSharePoint OnlineOneDrive for BusinessMicrosoft Graph
“We’ve identified a potential networking issue and are reviewing telemetry to determine the next troubleshooting steps,” it adds, noting any user serviced by the affected infrastructure may be unable to access multiple Microsoft 365 services.
For anyone still being affected by this issue, there could be good news soon.
Although there’s been no official confirmation, the Microsoft 365 service status page is showing no issues any more, with the cheery note that “everything is up and running”.
Outage reports are also falling on DownDetector following a massive spike earlier today – but until we’ve had an official tweet from Microsoft, it might not be worth getting carried away just yet….
Another update from Microsoft, which says it’s identified the cause of the issue now.
“We’ve isolated the problem to a networking configuration issue, and we are analyzing the best mitigation strategy to address it without causing additional impact. We’ll provide more information once we have additional information.”
It adds that some users will still be unable to access services such as Teams and Outlook, but that it is working on a fix.
More possible progress – the particular Microsoft 365 gremlin appears to have been identified…
We’ve rolled back a network change that we believe is causing impact. We’re monitoring the service as the rollback takes effect.January 25, 2023
