Microsoft said that it has fixed an issue in its Microsoft Office 365 service that sent regular emails to customers’ junk folders instead of their inboxes. 

“We’re looking into an issue where email is being delivered to the junk folder,” the business said in a 7.20 a.m. AEST statement. 

“We reversed [a] modification and witnessed successful email delivery,” the business announced at 8:47 a.m. 

“Any emails that were wrongly sent as junk are currently being reprocessed,” it stated. 

Since around 6.30 a.m., iTnews’ email accounts appeared to be disrupted, with emails being wrongly routed to junk.

Before the flaw was discovered, administrators reported attempting to resolve spam filtering settings on users’ accounts. 

It’s the second time in the last 12 hours that faulty spam filters have caused an issue with Office 365. 

Microsoft disrupted email forwarding for roughly three and a half hours last night, however, it was unlikely to have had a significant impact on A/NZ firms due to the timing. 

“We discovered that [the] impact is being caused by a freshly installed spam rule,” it claimed. 

“A fix has been produced and is being deployed to the impacted infrastructure.” 

In recent months, users of the cloud productivity suite have become accustomed to numerous difficulties and rollbacks. 

A big glitch earlier this month caused the body content of emails to be blank, and it took many hours to rectify. 

There have also been a number of lockouts caused by Azure Active Directory disruptions.
