As we entered the new year, many people welcomed 2022 by wanting to see what emails they had, maybe from relatives or preparing to get back to work after the festive season. However, many found their inboxes were suspiciously empty. That was because of a Microsoft Exchange bug that has been dubbed Y2K22.
The flaw was preventing Microsoft Exchange servers from sending emails. Luckily, Microsoft is acting quickly and the company is rolling out a fix. On the company’s Tech Community post to accompany the fix, Microsoft explains the situation and how it happened:
“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. “The version checking performed against the signature file is causing the malware engine to crash, resulting in messages being stuck in transport queues.”
According to the company, admins will need to use an automated script or run the fix manually for it to take effect. Microsoft admits it will take time for organizations and individuals to react and implement the fix. Furthermore, once the fix is implemented it may take time for emails to arrive in the inbox depending on how many are in the queue.
Users started complaining about email issues on January 1, and more people took to Reddit to confirm they also had issues. Bleeping Computer reports users were seeing error messages n the Exchange Server Event Log.
As there is no workaround, admins have been using alternative clients until Microsoft found a fix.
Of course, Microsoft was not without its problems during 2021. There were a series of vulnerability exploits endangering users on the platform.
In September, another major issue befell the platform. A security researcher from Guardicore found a major bug in Exchange’s Autodiscover protocol, resulting in nearly 100,000 login names and passwords leaking.
Tip of the day: Adding a new account in Windows creates a user profile, a collection of settings and folders that ensure each person on the PC has a unique, customized experience. This also contains all of their documents, saved games, videos, and more. This can take up some space, but fortunately, Windows lets you delete a user profile if you no longer need it or it gets corrupted.
