How do I check how much of my quota is used on my Exchange account?

Outlook Client:

  1. Open Outlook.
  2. Right-click on your mailbox folder (it will read "Mailbox - " for example: Mailbox - Cougar, Joe).
  3. Choose Properties or Data File Properties for Mailbox - .
  4. Click on the Folder Size button.
  5. The total size is what is used for everything you have on the Exchange server. It also lists the size of each individual folder below the total size.


Microsoft 365 on the web: 

  1. Click on the settings gear icon.
  2. Select Account.
  3. Select Storage.


Mailbox Features:

  • 99 GB quota
  • 35 MB message size limit including attachments
