Microsoft's silence, evident from a delay in alerting customers, compounded frustrations as administrators faced difficulties stemming from incorrect malware flags that quarantined legitimate emails.
While some reports suggest the flood of false positives has eased, issues linger as administrators are tasked with unblocking genuine emails manually, heightening the work load.
An amateur sysadmin points to a possible cause of the malfunction being related to Microsoft Defender's Threat Explorer tools, illustrating the complexity of malware detection systems.
Despite Microsoft claiming a fix for 99% of affected emails, the proactive communication approach relied upon by the company drew criticism for its timing and effectiveness.
