Allow all mailbox users to send emails up to 100 recipients (Exchange 2010)

Question

Greetings,
Could you please help on writing a Powershell script using Exchange Management Shell on how to realize the following:
I want to grant all recipients the ability to send emails up to 100 recipients, this rule will be applied by default to all mailboxes including the new created ones and the old ones.
FYI, i tried the following cmdlets from the organizational level:
Set-TransportConfig -MaxRecipientEnvelopeLimit 100 
This cmdlet did not applied to all mailboxes, because i have found some ones have unlimited RecipientLimits, some others have more than 100, newly created
mailboxes are unlimited by default !
Here is the cmdlet i have used to verify the
RecipientLimits one some mailboxes: 
Get-Mailbox -Identity
"username" | Select-Object RecipientLimits | fl
I want to force all users including the new and old ones to have RecipientLimits to 100, and if a user needs more than 100 i can grant him/her explicitly.  
Thanks in advance.

Thanks a lot, it works with all existing mailboxes, But not with new mailboxes which are unlimited by default.
I want this to apply to all mailboxes including newly created mailboxes.

Ask in Exchange forum to teach you how to create users from a template and set the template to the value you want.
The Transport limit superceded the user limit.  If the transport is set to 100 then ALL users are limited to 100.
This is why I recommend posting in the Exchange forum.  Don't ask how to write a script.  Ask how to set the limit in Exchange 2010.  They will give you a link to the appropriate documentation,  The issue I snot a scripting issue but
is a "how do I use Exchange " issue.  Asking the correct question will get you further.  Of course training in Exchange would be most helpful.
