How to get Mailbox usage using PowerShell in Exchange Online #PowerShell #ExchangeOnline

Hi Everyone,
In today's video, I will show how you can use PowerShell to Get UserMailbox or Sharedmailbox usage. They all show you the same result, with slight differences, and I used them a lot at work.

First Command

Get-Mailbox -Identity "MailboxName" | Get-MailboxStatistics | Select-Object DisplayName, ItemCount, TotalItemSize | Format-Table –autosize

Second Command

Get-Mailbox | Get-MailboxStatistics | Select-Object DisplayName, @{name=”TotalItemSize (GB)”;expression={[math]::Round((($_.TotalItemSize.Value.ToString()).Split(“(“)[1].Split(” “)[0].Replace(“,”,””)/1GB),2)}},ItemCount | Sort “TotalItemSize (GB)” -Descending
