If you woke up on January 1st, 2022, and found that your work email’s inbox was unusually empty, you aren’t alone. Microsoft rang in the New Year with a bug that prevents Exchange servers from sending emails, but fortunately, a fix has since been issued, as detailed in a report by Bleeping Computer.
“The problem relates to a date check failure with the change of the new year and is not a failure of the AV engine itself,” Microsoft explains in a post on its Tech Community forum. “The version checking performed against the signature file is causing the malware engine to crash, resulting in messages being stuck in transport queues.”
