Microsoft has decided to retract the Exchange security updates that were rolled out in November 2024, citing issues with email delivery.
Reports from administrators indicated a complete halt in email flow, prompting Microsoft to take action.
The problem primarily affects Microsoft Exchange users utilizing transport rules, mail flow rules, and data loss protection rules.
Customers reported intermittent disruptions in mail flow rules post-update installation, leading Microsoft to recommend uninstalling the security updates until a permanent solution is devised.
In an update, Microsoft assured ongoing efforts to resolve the issue and announced a temporary halt in the rollout of the November 2024 security updates.
