First, a little background. Our Human Resources team uses a cloud-based vendor for our payroll system. We pull information from that vendor daily to update some basic AD fields, create new users, etc. We manually use a powershell command to manually mail-enable the account in the morning, and then at noon another automated script moves the account to the correct OU so the account can be used. The reason for the delay is to catch quirky behavior...excessively long names, duplicate names, etc. What I'd like to know is how we can further automate this process based upon job description or other fields. For example, setting default quota limits on new users with a job title similar to 'Director', or something automated in the background which would automatically change the quotas from default to specified values if someone transfers into a position. But we have some users with the same title which have even larger mailboxes than the default for that role, so we don't want to reduce them. Are there powershell commands we can use to accomplish this, or some policy we can set where we can define this?

I ended up with this, not sure if it's the most efficient method but it seems to work. Do we need to run this manually moving forward or is there a way to automate running this for future people who match? get-user -resultsize unlimited -filter {(Recipienttype -eq 'UserMailbox') -and ((title -like 'Community Director') -or (title -like 'Senior Community Director'))} | get-mailbox | where {($_.UseDatabaseQuotaDefaults -eq $true)} | set-mailbox -ProhibitSendReceiveQuota 200MB -ProhibitSendQuota 170MB -IssueWarningQuota 150MB -UseDatabaseQuotaDefaults $false

Maybe out that in a script and configure a scheduled task.Sukh

Save it as a .ps1 file and run as a scheduled task.

Which version of Exchange, for e.g 2007/2010 You can use the get-mailbox and use customer attributes or any other attibute here -http://technet.microsoft.com/en-us/library/bb430744(EXCHG.80).aspx , then pipe that to set-mailbox and set the quotas.Sukh

Exchange 2010 SP1. I'll see if I can figure out the syntax to apply quotas to directors who are at defaults.
