As explained in Throttling Policies and the EWSFindCountLimit, there was an EWSFindCountLimit throttling policy you could set in Exchange 2010. When I look at the parameters for New-ThrottlingPolicy for Exchange 2013, I don't see EWSFindCountLimit. Is this still something that can be set, just via another mechanism, or is EWSFindCountLimit gone in Exchange 2013?

Hi amythorne, I check the parameter in my lab, and it doesn't exist, either. I am trying to involve someone familiar with this topic to further look at this issue. If you have any feedback on our support, please click here Frank Wang TechNet Community Support

Hi amythorne, EWSFindCountLimit is gone from cmdlet and EWS tuning parameters are as below EwsCutoffBalance EwsMaxBurst EwsMaxConcurrency EwsMaxSubscriptions EwsRechargeRate http://technet.microsoft.com/en-us/library/dd298094.aspx
