Thursday, Nov. 12, Microsoft re-released KB 3097877 — the horribly messed-up security patch freezes Outlook. Clients have complained about HTML emails freezing.
The problem is with software in one of the four critical patches issued in yesterday’s Patch Tuesday bundle – MS15-115. This was supposed to fix a flaw in the way Windows handles fonts, but has had some unexpected side effects for some Outlook users.
