Exchange Online: Legitimate emails quarantined due to bug

Microsoft is currently investigating a new bug that is causing some users’ emails in Exchange Online to be quarantined. It seems that the spam filters in Exchange Online are mistakenly flagging certain emails as spam and moving them to quarantine. This issue was initially reported by platform administrators earlier today, but it has now affected a significant number of systems. While Microsoft hasn’t specified which regions are most affected, the notification message regarding the problem is classified as “Critical,” which typically indicates a serious issue that needs to be resolved.

According to Microsoft, some emails received by the system are being incorrectly marked as spam, leading to their inadvertent quarantine. This can happen randomly, even with messages that should be considered safe and pass through the spam filters without any issues. Interestingly, the problem seems to occur more frequently with emails containing specific URLs, which are being classified as spam. Even if system administrators add these links to the whitelist, the messages can still be filtered out.

To make matters worse, there is an additional problem on the platform that prevents some administrators from viewing the messages that have been quarantined. This further exacerbates the situation. Users have been reporting this flaw for over two days, but it’s only now that Microsoft has acknowledged it.

Unfortunately, there is currently no effective solution for this problem. Administrators will have to wait for Microsoft to implement a fix on their end. It’s certainly frustrating for those affected, but it’s important to remember that bugs and glitches are a part of technology. The best we can do is be patient and trust that the experts at Microsoft will resolve the issue as quickly as possible.
