Microsoft has released an emergency fix to tackle a date-check bug found in Exchange on-premises servers. In a blog post on January 1, Microsoft stated that customers interested in using the fix will have to implement it themselves.
To address the problem, Microsoft officials provided automated and manual solutions, explaining that the time needed to execute the scripts will vary depending on the size of the organization.
The error, which began on January 1, 2022, caused messages to get stuck in Exchange 2016 and 2019.
In its statement, Microsoft explained that the problem was caused by an error in the date-check failure. The company found that the version verification performed on the signature file caused the malware engine to crash, causing messages to get stuck.
Microsoft confirmed that it is working on a new on-premises version of Exchange that would require a mandatory subscription for anyone interested in receiving security and other updates to the product.
