Microsoft’s Exchange Update Fiasco: When “Patch Tuesday” Becomes “Stop Everything Wednesday”
Microsoft pulled the November 2024 Exchange security updates due to email delivery chaos on servers using custom mail flow rules. Admins reported that emails stopped flowing entirely. If you’re not using transport or DLP rules, you’re in the clear. Otherwise, it’s time to play the waiting game for a fix.

Hot Take:
Microsoft’s November 2024 Exchange updates took a detour faster than a GPS-leading you into a lake. If your email delivery is as reliable as a carrier pigeon with a broken wing, you might want to hold off on these updates. But hey, at least your sensitive info won’t leak out… because it won’t go anywhere at all!
Key Points:
- Microsoft paused November 2024 Exchange updates due to email delivery issues.
- The issue affects servers using custom mail flow or DLP rules.
- Admins experiencing issues are advised to uninstall the updates.
- A high-severity vulnerability (CVE-2024-49040) was disclosed, allowing email spoofing.
- Four zero-days were addressed in the November 2024 Patch Tuesday.
