There may be times when you want to remove the Exchange Throttling policies for a user in order to troubleshoot an issue.
To remove it for a user we first of all need to create a new throttling policy which has no limits applied to it. In my example I have called the policy “NoThrottling”. Open up an Elevated Exchange PowerShell session and run the command :
We have now created a blank Throttling Policy. We now need to set it to Unlimited :
Set-ThrottlingPolicy NoThrottling -RCAMaxConcurrency Unlimited -EWSMaxConcurrency Unlimited -EWSMaxSubscriptions Unlimited -CPAMaxConcurrency Unlimited -EwsCutoffBalance Unlimited -EwsMaxBurst Unlimited -EwsRechargeRate Unlimited -DiscoveryMaxConcurrency Unlimited
Then last but not least assign the policy to the user.
set-mailbox Username -ThrottlingPolicy NoThrottling
