Why doesn't mailbox size defaults in Exchange 2010 apply to all users?

Posted on 2014-09-02

I have the default mailbox size set to warn users at 6500MB. But users are not being limited. I used the get-Mailbox -Identity to check the size of a user mailbox and here's what I got:
IssueWarningQuota        : unlimited
ProhibitSendQuota        : unlimited
ProhibitSendReceiveQuota : unlimited

The user does have the storage quota set to "Use mailbox database size"

Setting the warning quota alone will not impose any limits on the mailbox. It simply issues a warning. You need to set the prohibit send and/or prohibit send/receive quotas if you want to impose limits.

What value do you have set for the ProhibitSendQuota?

you would add the stop send or stop send & receive quotas on the actual mailbox database storage volume -- on the EMC under Organisation Config --> Mailbox, you should have your database(s) listed for you mailboxes.

In the Properties, click the Limit tab and then set your required numbers.  You can also set config for deleted items and mailboxes.

Then comes the tedious bit, to verify a few mailboxes and make sure their Mailbox Settings-->Storage Quota is set to Use Database defaults and your all set.  You can enforce immediately if you restart your Info Store Service, or leave it overnight and your staff will have fun in the morning when they realise they are over quota!!!
