Microsoft releases official fix for Y2K22 Exchange Server bug that was causing mail jam

System administrators looking over Microsoft Exchange servers probably haven’t had the most joyous start to their new years.

As a result, the malware checking engine is crashing, and consequently, emails and messages have been stuck in transport queues across Exchange Servers 2016 and 2019 with Application event log errors 5300 and 1106 (FIPFS).

Microsoft said that it was aware of the problem and was working on a fix.
