Bleeping Computer reports the company has released a temporary fix for a bug that broke email delivery for on-premises Exchange and servers on New Year's Day.

As users discovered, Exchange was trying to store version date checks for its antivirus scanning engine in a bit integer variable — a big problem when any date from January 1st, onward was too large. Any new checks made the malware engine crash and left email stuck in a queue. The emergency fix uses a PowerShell script to pause two services, replace the older antivirus engine files with newer ones that use a new number sequence, and restart operations.

The fix requires manual input and could take a long time to implement for larger companies, but an automatic solution is in development.
