Setting Max Recipients for multiple mailboxes in Exchange 2007

We set the Global Max Recipients attribute in Exchange 2007 to 1600. This however can only be used by a chosen few. We have over 1500 mailbox users. Is there a way to change the Max Recipients atrribute for all those mailboxes(minus those who can) without doing it one by one? I assume that I cannot set the global maxrec to 100 and then set the chosen few to 1600.

Assistance is appreciated.

Thanks

jt.

Hello,

If you would like all your users to have the Global Max Recipient setting, run this powershell script to set the recipientlimits at the account level to unlimited.

Get-Mailbox -ResultSize unlimited | % {
	Set-Mailbox $_.alias -RecipientLimits unlimited
}

Open in new window


You can then set the RecipientLimits on individual mailboxes to a higher or lower value than the global value if you want to set exceptions of specific mailboxes.

Restrict the Number of Recipients per Message

This article explains different levels to set and locations so yes it has to be global or at Connector level and then you can set it Low on all Users and then Explicitly have it higher on few users

To add to comments from JJ, i would say set the limit to 100 with this command or how i said and then if you have something common for other set of users maybe they are members of a DL or some common attribute you can set them a higher value with a shell command again

Get-Mailbox | Where {$_.Department -Like "IT"} | Set-Mailbox -RecipientLimits unlimited
