The Outlook spam filter system has a malfunction, and a large number of users are being bombarded with spam emails
Last night, Microsoft Outlook experienced a malfunction where the normal sending and receiving of emails was not affected, but the spam filter system malfunctioned, causing users to receive a large amount of spam emails.
This problem was found to have occurred in both Outlook.com and Hotmail, where the spam filter system did not work properly, but the filter system in the Outlook client was normal and could still filter emails.
Thanks to the client’s synchronization feature, spam emails that arrived at the Outlook client were also synced to the cloud after being judged, but users who used other clients could only be bombarded with spam emails.
A large number of users also reported this issue in the Outlook community. It wasn’t until around 6:40 a.m. this morning that Microsoft announced that the filter problem had been fixed.
Microsoft did not specify the cause of the problem, but this filter issue is likely to have made spam senders very happy as a large number of spam emails were seen by users.
Therefore, users should be vigilant against potential phishing emails, not download attachments in emails, and not enter sensitive information such as account passwords in links.
