Microsoft said it has moderated an issue in its Office 365 service that automatically routed regular messages straightforwardly to clients’ junk folder rather than to their inbox.
“We’re investigating an issue in which email is being sent to the junk folder,” the company said in an advisory at 7.20am AEST.
The organization said at 8.47am that it had “reverted [a] change and observed successful email delivery.”
“We’re now reprocessing any emails that were incorrectly delivered as junk,” it said.
iTnews’ own email accounts appeared to be affected, with emails being erroneously directed to junk since about 6.30am.
Enterprise clients would be very much encouraged to check their junk folders for the past few hours.
Administrators announced attempting to troubleshoot spam filtering settings on clients’ accounts before the bug was recognized.
It is the second issue in the previous 12 hours with Office 365 that was brought about by the presentation of errant spam rules.
In spite of the fact that it was probably not going to have affected A/NZ businesses extraordinarily inferable from the timing, the previous evening Microsoft broke email sending for around three-and-a-half hours.
“We determined that a recently deployed spam rule is causing [the] impact,” it said.
“We’ve prepared a fix and are deploying it to the affected infrastructure.”
Clients of the cloud productivity suite have gotten familiar with continuous issues and rollbacks in recent months.
A significant issue earlier this month rendered the body text of emails blank, and was not resolved for various hours.
There have likewise been a series of lockouts because of blackouts of Azure Active Directory.
