Microsoft 365 Has Been Flagging Good Emails as Junk

Microsoft says the Microsoft 365 issue was caused by a change it recently made and has now rolled back to mitigate the problem.


Users of 365 may not be receiving their emails properly today. Microsoft says on Thursday morning a problem with emails is causing emails to be labeled incorrectly. Many legitimate and important mails are being sent to the junk folder.

Microsoft has confirmed the issue this morning:

“We're investigating an issue in which email is being sent to the junk folder. We'll be providing updates under EX258373 in the admin center,” Microsoft tweeted on the 365 status account at 7:25am AEST.

About an hour after the first report, the team said the error is happening because of a behind the scenes change to the platform. However, Microsoft said it was rolling back to mitigate the issue:

“We're reverting a change that has caused inbound email to be incorrectly routed to the junk folder. Additional information can be found in the admin center under EX258373.”

Later, Microsoft returned to say the change had been rolled back. Now the company is working to put incorrectly labeled emails back where they belong:

“We've reverted the change and observed successful email delivery. We're now reprocessing any emails that were incorrectly delivered as junk. More info can be found in the admin center under EX258373,” another update at 8:47am AEST added.

Exchange Online Issue

Microsoft 365 started having email problems on Wednesday night. Users were complaining they were unable to forward emails on . In a tweet, Microsoft said a spam rule it created was the root of the problem:

“We've prepared a fix and are deploying it to the affected infrastructure. For more details, please visit the admin center.”

Microsoft said the issue was resolved later in the night.
