We hope everyone had a wonderful New Year but unfortunately for those with 2016/2019 Exchange servers, the turning of the clocks to 01/01/2022 led to an unpleasant bug.
Computer bugs related to a New Years event aren’t uncommon, we created this infographic about other times this has happened (as well as a notable future one).
The error this time was caused by the date checking within the anti-malware portion of Exchange.
