Increasing the Rules Quota limit in Exchange Server 2007

Share this:

Hello folks,

In the previous versions of Exchange Server we cannot play with the mailbox rules limit that is only 32kb ( Using Exchange Server 2007 we can do that through Exchange Management Shell. Let’s see how to do that..

The cmdlet utilized to set up the mailbox is called set-mailbox: 

Set-Mailbox <mailbox> -RulesQuota:<size>

Let’s change the user Alexandre to 256KB limit using set-mailbox, and after that let’s visualize the changes, as it follows:


Ps.: This value is only for enabled rules, the disabled rules are not included in the amount of rules data.

Best Regards,
Anderson Patricio
