Can't get the value of publicdelegatesbl in a variable

Question

Hello,
When a mailbox is disabled if the user was as a delegate in another mailbox and that the user didn't remove him from his delegate, he'll see a unknown SID in his delegate. In order to prevent this I would like to run a script that will remove delegatebl
of that the user who would be disabled.
Servers are on Exchange 2007 SP3 RU6. No powershell V2 is installed... only V1. That's my main problem. I have the Quest cmdlet installed. I can only used them.
I wrote a script but my problem right now is only to get the value publicdelegatebl in a variable... I have a blank return...
$QADUser = (Get-QADUser "$User" -IncludedProperties publicdelegates,publicdelegatesbl).publicDelegatesbl
Write-Host $QADUser
Any help please?

Answer 1

Thanks it worked... but now when I am trying to remove the publicdelegatesbl I have a constraint violation error. I understand what you've told me about the fact we cannot clean up the message without using outlook. But is there any other solution except
Outlook? I meant even with the EWS it's not possible? 
Currently I have to be able to remove the delegate added by outlook and by scritpt...
