There has been a problem with Azure Active Directory as a result of which all the users of Microsoft around U.S. have been locked out of their Microsoft 365 accounts recently and that also halted their businesses.
The Twitter feed for the Microsoft 365 Status said that they are investigating an issue that has affected the access to the services of Microsoft 365. They are working to identify the impact and would provide information shortly.
Microsoft stated in the Microsoft 365 Service health status page that they identified the problem and were reverting a recent change as an attempt to solve this issue.
An IT Director told CRN that all the employees of his company were locked out of the services of Microsoft 365 which also included Outlook email.
Microsoft customers started to report the inability of accessing Microsoft 365 on Downdetector.com within an hour and more than 18,000 posts regarding this problem flooded their website which also tracks cloud outages.
Azure Active Directory is the identity of Microsoft and access management service by which users can sign in to their cloud accounts.
Microsoft said in the Microsoft 365 Service health status page that existing sessions were not affected by the outage.
The page said that the affected users were asked to keep the existing sessions going on and avoid the re-authentication of Microsoft 365 services. A Microsoft 365 service which leverages the authentication of Azure Active Directory might get affected by this issue.
