Yesterday I received email from MS to download and install "Update for Windows Live Essentials Mail 2012 (KB3093594)" in order to allow WLM2012 to continue to work with Outlook.com based email.

This patch BREAKS Windows Live Mail 2012, causing the application to crash.  I am not alone in this experience, and the only way to make WLM2012 work is to roll the system back or completely reinstall the program.

I am running Windows 10 Pro and prior to this patch WLM2012 worked flawlessly.  After rolling back via backup, it works again.

This patch needs to be withdrawn and fixed.  Terrible work here, Microsoft!
