Get mailbox size exchange 2007

How to get mailbox size in exchange 2007 via PowerShell.
Very simple!
1. If you need to check mailbox size for individual use string bellow:

Get-MailboxStatistics username | ft DisplayName, TotalItemSize, ItemCount
******for more information use get-help Get-MailboxStatistics -full******

2. If you need to get mailbox size for all user use next command:

Get-MailboxStatistics | ft DisplayName, TotalItemSize, ItemCount
******To export output to the file, add > c:\mailboxsize.txt******

FOR EXAMPLE:  Get-MailboxStatistics | ft DisplayName, TotalItemSize, ItemCount > c:\mailboxsize.txt

To view more friendly output you can try to use my string:

Get-MailboxStatistics | Sort-Object TotalItemSize -Descending | ft DisplayName,@{label="TotalItemSize(MB)";expression = {$_.TotalItemSize.Value.ToMB()}},ItemCount > c:\mailboxsize.txt

:)

******If the command is not working run this before:******
