Thanks for the link. I found that yesterday, but it only returned on-premise mailboxes for some strange reason.

Hi fellow experts,<br />
<br />
We have an Office 365 environment with rich co-existence (on-site exchange 2010 for management) with our sub-domain on office 365 plus an additional domain.<br />
<br />
I need to get mailbox sizes of the mailboxes in Office 365, but running &quot;Get-Mailbox | Get-MailboxStatistics | Export-CSV C:\O365mailboxes.csv&quot; only returns on-premise information, rather than the mailboxes within Office 365. <br />
<br />
Any ideas, how I can accomplish this please?<br />
<br />
Thanks.
