The Inquirer warns one of the patches Microsoft distributed earlier this week is causing issues with Outlook. The patch fixed some security bugs but caused other things to stop working in Outlook 2010 and 2013:
The first report says that HTML messages were causing Outlook to crash on both the 2010 and 13 Outlook clients. It suggests that the kind of messages that cause the issues are the kind of messages that no one really wants.
"They were always HTML messages, typically the sort of '[on sale' e-mail you get from distributors etc that include a lot of tables, images etc," it said. "I removed KB3097877 & KB3101746 and I've not been able to reproduce the crashes on 2 PC's since."
Other posts confirm the same issue, and that the removal of the above elements of the patch whack had a positive impact on performance. Microsoft must have been reading. It has updated the information on KB3097877, adding in a note about the issue and its remedial work.
