Ever since we upgraded Exchange 2010 to SP1, our CA ARCServe backups have been erroring out. CA's tech support said I had to run the following commands regarding Throttling Policy New-ThrottlingPolicy "ARCserveDocLevelPolicy" -RCAMaxConcurrency $null -RCAPercentTimeInMailboxRPC $null -RCAPercentTimeInCAS $null -RCAPercentTimeInAD $null. Set-Mailbox BACKUPACCOUNT -ThrottlingPolicy "ARCserveDocLevelPolicy" I believe I ran them successfully the first time but but I can't remember if I ran them in teh Exchange power shell or the Windows powershell. Now when I if I want to make a change to the policy, a message keeps coming back saying the policy already exists. To make a change, do I have to remove the existing policy and then run the New command?

yes .. you ran New-ThrottlingPolicy to policy to create new policy. when you want to modify anything in the policy you have to use "Set-ThrottlingPolicy" http://technet.microsoft.com/en-us/library/dd298094.aspx DhruvDhruv
