Exchange 2013 Mailbox usage problem

I just finished my Exchange migration from 2007 to 2013  I had some issues and still working through some, but I've never seen this before. On some mailboxes, exchange increased the storage limit on it's own. I don't know why or how, but this is a problem, because my mailbox database size doubled from 2007 to 2013. For example, on my own mailbox size, it was set to 5GB when in exchange 2007, but now, it's 35.15GB and I have never increased it to that amount.

I have attached a picture for clarification purposes.  What do I do to make sure this doesn't happen again, and is there a powershell command I can run that shows me all users and their mailbox size limit, so I can go and reduce the size?

You can run the following from your Exchange Mailbox Server in the Exchange Management Shell

Get-MailboxDatabase | Get-MailboxStatistics | Sort totalitemsize -desc |  Select database,displayname,@{expression={$_.TotalItemSize.Value.ToMB()}},itemcount | export-csv 'c:\mailboxstatistics.csv'

Great, thank you, that worked, but now, how do I avoid this from happening again?  If it once just increased the mailbox sizes, is there a configuration somewhere where I can ensure this doesn't occur again?

Can you adjust the script to also show the total mailbox size as well, as this way, it's much easier to just see where the problems are at, instead of going through each and every individual mailbox.

Thanks for your help, if at all possible, is there a way to add the field to your above command that also shows the user's total mailbox size allowed?
