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.<\/p>\n\n\n\n
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.<\/p>\n\n\n\n
The error, which began on January 1, 2022, caused messages to get stuck in Exchange 2016 and 2019.<\/p>\n\n\n\n
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.<\/p>\n\n\n\n
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.<\/p>\n\n\n
