Warning: We do not recommend removing security updates as a workaround for this issue.


The Outlook Team is investigating the issue.

As a workaround, you can manage rules in Outlook Web Access (OWA).  If you use Outlook Web Access to edit the rules, please avoid running Manage Rules & Alerts... in Outlook or the error will return. 

Warning:  When you create, modify, remove, enable, or disable in Outlook Web App, some rules that are send rules and currently disabled rules will be deleted. If you need to preserve the client side rules please wait for the fix to be released.
