Microsoft Outlook for Windows - Check Your Mailbox Size

Please keep the size of your Microsoft Outlook mailbox as low as possible and remove information from it as soon as you receive a mailbox size warning message.

To check the size of your Outlook mailbox at any time, follow these steps:

  1. Right-click on OUTLOOK TODAY in the folder list on the left side of your Outlook window.

  2. Choose the PROPERTIES option from the drop-down list that appears.

  3. Click on the FOLDER SIZE… button on the GENERAL tab.

  4. The TOTAL SIZE figure is the total amount of space your mailbox is using on the e-mail system. (Example: 4,243K = 4.2MB) 

You can also see the size of each individual folder in the window below the total.
