*This story is ongoing and will be updated. Microsoft has had a lot of security problems in the past few years, with DDOS attacks and other system malfunctions occurring on an alarmingly regular basis. So when Microsoft 365 Admin began sending notifications to users’ phones at about 8:15PM, on Thursday, December 2nd, it raised some eyebrows.
Notifications received by many Microsoft Admin App Users
The text of the notification read “Microsoft 365 Admin – Microsoft OneDrive & SharePoint Library Dropdown menu” – no additional information was given as to what this meant or why these notifications were being sent out. From social media posts by those who received them, we can see that many people are wondering if their accounts have been hacked or if there is some other explanation for these Microsoft Message Center notifications. Microsoft chimed in on Twitter at 8:43PM on the topic stating they are looking into the issue:
We're investigating reports of an issue with repeated admin notifications flooding mobile devices. Some admins are also experiencing delays or unable to open admin center. We'll provide additional information shortly.
