Exchange 2007 individual mailbox quotas

I have Exchange 2007 and I need to setup some mailbox quotas on some users.  Basically, I will set most people to be limited to 3 GB, another group of people will be limited to 5 GB, and the Excutives and IT team will be set to a 10 GB limit.

I saw where I can do this on Exchange Console under the individual mailboxes, but when I look at AD it tells me that this quota size is not permitted.

1.  Can I set mailbox quotas greater than 2 GB in Exchange 2007 and have it work?
2.  Is there a utility that will allow me to modify multiple people at once?

I did this with 2003 using adsiedit, but don't know if it will work with Exchange 2007.

1. Yes, you can only see Exchange 2007 attributes in either the Exchange Console or Shell, not ADUC
2. Yes, you can use PowerShell

Set-Mailbox -ProhibitSendReceiveQuota -ProhibitSendQuota -IssueWarningQuota

if you have a list of users in a text file you can run

Get-Content c:\users.txt | Set-Mailbox -ProhibitSendReceiveQuota 5GB -ProhibitSendQuota 3GB -IssueWarningQuota 2GB

easiest way to do this is with multiple mailbox databases.
in the EMC go to Server Configuration > Mailbox
then under database management create separate mailbox databases for each, set your limits there, then move the users to the database you want them in

not sure how high you can go. as you can see in the pic, mine is set at 1.5GB

Easiest way I think is to have separate mail databases. Then set the limits on the DB. All users put in the DB get the policy without any monkeying around with stuff. If they need more space the get a mailbox move to the other DB....no worries!!

i agree with the others that the database limits is the best way to implement quotas
the powershell commands i gave were to quickly resolve the issue without moving mailboxes to different databases
