Exchange 2013 throttling

When setting up a special user that is used to copy a lot of items we today learned about the default throttling restrictions in Exchange 2013.

Here’s so useful powershell commands for the occasion.

/>get-throttlingpolicyassociation john.doe |fl      - shows what policy is associated with account. If it’s empty it’s the global default.

To Check the current throttlingpolicies:

/>get-throttlingpolicy |fl

To create a new one and set it to unlimited

/>New-ThrottlingPolicy MyNewPolicy

/>Set-ThrottlingPolicy MyNewPolicy -RCAMaxConcurrency Unlimited -EWSMaxConcurrency Unlimited -EWSMaxSubscriptions Unlimited -CPAMaxConcurrency Unlimited -EwsCutoffBalance Unlimited -EwsMaxBurst Unlimited -EwsRechargeRate Unlimited

/>Set-Mailbox "john.doe" -ThrottlingPolicy MyNewPolicy

Goes without saying that this should be used with extreme caution.
