To be clear, I'm asking this as someone with an Exchange e-mail account, not an Exchange administrator.

I've poked around in box Outlook and Outlook Web Access but I don't see where this information is displayed. All I know is that when I do run out of space I get an e-mail message telling me my box is full...

Here is a step by step guide but basically you right click on the mailbox and click properties.

According to this there is a faster way:

  • Tools
  • Mailbox Cleanup
  • View Mailbox Size

Sweet! This is at least half of what I'm needing, I can now see how much storage I'm using... I still don't see how much space I have left / total space available though. Do I just need to find out from an administrator how much they've allocated my account? – silent__thought Jul 31 '09 at 16:29
Correct. The default is normally around the 500MB - 1GB range. Just pop them an e-mail and ask. Or it would be somewhere in the company computer use policy. – BinaryMisfit Jul 31 '09 at 16:32

In Outlook, right click on your root 'Mailbox' folder and click Properties.

On the 'General' tab, there's a button called 'Folder Size...' - click this button.

The window that then pops up has a 'Server' tab which gives you all the information you need.

(Note that these instructions were written using Outlook 2007)

It varies depending upon which Outlook client you're using.

In Outlook for Mac (Office 365 version, which is also Outlook 15), you right-click the Inbox (or other folder you want to inspect), choose Properties, then select the Storage tab.
