Script to change Address Book Service throttling on Exchange 2010

  • Artikel

If you are deploying BlackBerry in Exchange 2010 environment, one of the requirements is to change throttling limits on Address Book Service from default 50 to 100,000. While I reserve my judgment to what number is right, you will have to change it to some number above 50 for sure.

If you have many CAS servers where you have to change this, it quickly becomes painful because you have to change config file and restart services.

Well, sweat no more if you are in this situation. Use my script instead.

You can download the script here: Set-ThrottlingLimit.ps1

I will avoid posting entire code here but below are some examples of how you can run it:

The following example will query specified server for current value of MaxSessionsPerUser:

 

 Set-ThrottlingLimit -Server Server1

 

The following example will set MaxSessionsPerUser to 5000 and restart services MSEXchangeRPC and MSExchangeAB without confirmation:

 

 Set-ThrottlingLimit -Server Server1 -MaxSessionsPerUser "5000" -force $true

 

The following example will set MaxSessionsPerUser to 5000 and restart services MSEXchangeRPC and MSExchangeAB after confirmation from user:

 

 Set-ThrottlingLimit -Server Server1 -MaxSessionsPerUser "5000"

    No, this does not apply to SP1. I will be updating the script to account for changes in SP1.

    Good script.  Timely, too, as I just finished configuring the BES Service Account on Exchange 2010. What would have been helpful to include, however, is: Sign the script (default ExecutionPolicy is RemoteSigned) or Instructions on how to run unsigned Elevated PowerShell Instance  Set-ExecutionPolicy Unrestricted  Run script (.Set-ThrottlingLimit.ps1 <arguments>)  Set-ExecutionPolicy RemoteSigned Instructions on how to add the script permanently so when you open EMS, it loads automatically.

    Does this apply for E14 Service Pack 1 as well?
