The mo1465962 tag on WindowsForum.com tracks discussion of a specific Microsoft Defender for Office 365 service incident. Coverage centers on Microsoft resolving an issue that incorrectly blocked legitimate Google Search links, with the original reports of an active investigation now outdated. The incident ran for several hours on September 2, 2026, according to Microsoft's final service-health update, and the company corrected the bad URL reputation classification behind the blocks. Notably, the problem did not involve the Microsoft Defender Antivirus client built into Windows; it affected Safe Links, the cloud-based link protection feature in Defender for Office 365.
