Exchange CmdLet Error

Hi! 

Im wondering if anyone else had any problems catching specific errors from Exchange 2010 cmdlets? It seems like no matter what I do the only way to catch an error is by not specifying the error type.

Im guessing it has something to do with Exchange cmdlets using a remote session?

Example that works:

try
{Get-DistributionGroup -Identity 'DoNotExists' -ErrorAction Stop}
catch{ Do something } 

But what I really want is to catch specifik errors for example: 

Grop 'DoNotExists' returned 6F0E11E5,Microsoft.Exchange.Management.RecipientTasks.GetDistributionGroup 

I guess I could always do something like this:
try {Get-DistributionGroup -Identity 'DoNotExists' -ErrorAction Stop}
catch
{
if ($_.Exception -Match "*Error message...*")
   {
       # Do something about it
   }
}

But there must be a "correct" way to catch Exchange cmdlet error types?
I would really appreciate if someone could guide me in the right direction, thanks!
