Hi All, Just trying to confirm if you can set mailbox size limits to a mailbox depending on which mailbox RoleAssignmentPolicy the user is in? We currently move users from one DB to another simply to change mailbox sizes. I would like to set these limits based on which policy the mailbox is in. Thanks

Hi Sgt Josh, Yes, you can. Please try the following cmdlet: Get-Mailbox | where {$_.RoleAssignmentPolicy -eq "policyname"} | Set-Mailbox -IssueWarningQuota 209715200 -ProhibitSendQuota 262144000 -ProhibitSendReceiveQuota 293601280 -UseDatabaseQuotaDefaults $false Set-Mailbox http://technet.microsoft.com/en-us/library/bb123981.aspxFrank Wang TechNet Community Support

Thanks Frank, but I would prefer not too run script every hour for this too work I would like this to occur dynamically meaning if a user has change to a new policy the new limit is set strait away. Is this possiable? Thanks Josh

Hi Sgt Josh, Usually, you can do it via Schedule Task to run an Exchange task automatically. Please see the following blog: How To: Schedule PowerShell Script for an Exchange Task http://exchangeshare.wordpress.com/2008/12/08/how-to-schedule-powershell-script-for-an-exchange-task/ Another choise is to create several .ps1 file to combine two tasks: Set-Mailbox with RoleAssignmentPolicy & Set-Mailbox with *quota. If you want to change a new policy for a mailbox, you can use the .ps1 file to do it.Frank Wang TechNet Community Support

Hi Sgt Josh, Any updates?Frank Wang TechNet Community Support

It'll work but it's not really what we wanted as the helpdesk should not have to tell the user that there is an or so hour delay, and as we would like to have a number of policies and we have a large user base it would create unnecessary load on our DC's. So basically we have to weigh up the cost.

Are we happy to say that no other way to complete this action?

Hi Sgt Josh, Yes, I'm afraid you have to rely on the above two options at the moment.Frank Wang TechNet Community Support
