In order for Symprex Out-of-Office Extender to function correctly on Exchange Server 2010 and 2013, it is necessary to disable client throttling for the service account. This can be accomplished as follows:
1. | Open the Exchange Management Shell and connect to Exchange Server.
|
2. | Type the following command:
New-ThrottlingPolicy <Policy>
where <Policy> is a suitable, unique name for the policy (for example, OOXServiceAccountPolicy)
|
3. | On Exchange Server 2010, type the following command:
Set-ThrottlingPolicy <Policy> -EWSFastSearchTimeoutInSeconds $null -EWSFindCountLimit $null -EWSMaxConcurrency $null -EWSMaxSubscriptions $null -EWSPercentTimeInAD $null -EWSPercentTimeInCAS $null -EWSPercentTimeInMailboxRPC $null
|
4. | On Exchange Server 2013, type the following command:
Set-ThrottlingPolicy <Policy> -EwsCutoffBalance Unlimited -EwsMaxBurst Unlimited -EwsMaxConcurrency Unlimited -EwsMaxSubscriptions Unlimited -EwsRechargeRate Unlimited -IsServiceAccount:$true
|
5. | Type the following command:
Set-Mailbox <Account> -ThrottlingPolicy <Policy>
where <Policy> is the name of the policy and <Account> is the name of the service account to which the policy will be assigned. |
Note Changes to client throttling policies will not be applied immediately on your Exchange Server; please allow some time for the changes to become effective.
