Adjusting throttling policies

Follow these steps to associate a new throttling policy that does not enforce restrictions for listener accounts.

About this task

If you set up throttling policies in your environment, the listener accounts might be affected by these policies and email notifications might not work well. To avoid issues with throttling policies, create a new throttling policy that does not enforce limits on listener accounts.

Note: For all listener accounts, you must associate a new throttling policy that does not enforce restrictions.

Procedure

  • For Exchange 2010, follow these steps:
    1. Log on to the Exchange Server as the administrator, and then open the Exchange Management Shell.
    2. At a command prompt, type the following command to create and set a new throttling policy: New-ThrottlingPolicy MaaS360ThrottlingPolicy -EWSMaxConcurrency $null -EWSPercentTimeInAD $null -EWSPercentTimeInCAS $null –EWSPercentTimeInMailboxRPC $null -EWSMaxSubscriptions $null -EWSFastSearchTimeoutInSeconds $null -EWSFindCountLimit $null
    3. Type the following command to disable policy enforcement: Set-Mailbox "<userid>" -ThrottlingPolicy MaaS360ThrottlingPolicy
  • For Exchange 2013+, follow these steps:
    1. Log on to the Exchange Server as the administrator, and open the Exchange Management Shell.
    2. At a command prompt, type the following command to create a new throttling policy: New-ThrottlingPolicy MaaS360ThrottlingPolicy
    3. Type the following command to set the throttling policy: Set-ThrottlingPolicy MaaS360ThrottlingPolicy -RCAMaxConcurrency Unlimited -EWSMaxConcurrency Unlimited -EWSMaxSubscriptions Unlimited –CPAMaxConcurrency Unlimited -EwsCutoffBalance Unlimited -EwsMaxBurst Unlimited –EwsRechargeRate Unlimited
    4. Type the following command to disable policy enforcement: Set-Mailbox "<userid>" -ThrottlingPolicy MaaS360ThrottlingPolicy
  • For Office 365, the administrator does not have control over throttling policies for Office 365. The EWS uses the standard throttling limits set on the Office 365 tenant and the MaaS360® listener accounts work accordingly.
