Microsoft is presently looking into an authentication error hitting its Office 365 systems.
” Starting at approximately 21:25 UTC, a subset of consumers in the Azure Public and Azure Government cloud may come across errors performing authentication operations for a number of Microsoft/Azure services, including access to the Azure Portals,” the company stated in a status post.
In another post, the business stated users would be not able to access Office.com, Outlook.com, Teams, Power Platform, and Dynamics365.
” Existing consumer sessions are not impacted and any user who is logged in to an existing session would have the ability to continue their sessions,” Microsoft said.
On its Twitter status account, Microsoft said the source seemed a current modification, which it had chosen to roll the change back.
” Weve rolled back the change that is likely the source of impact and are monitoring the environment to verify that service is recuperating,” the company said, before following up 14 minutes later on to say it was not seeing what it expected to see.
” Were not observing an increase in successful connections after rolling back a current modification. Were working to assess additional mitigation options while we examine the source.”

By 00:40 UTC, Microsoft stated it was seeing enhancement across multiple services..
” Were continuing to see substantial enhancement for afflicted services and most users need to be experiencing relief,” Microsoft included at 1:20 UTC.
