Q: How do I check my Exchange email quota?


Your Exchange Quota is 23 GB and includes all your email, attachments, calendaring data, task items, and more. We strongly recommend you manage your quota by archiving old messages to your personal computer and deleting items you do not need.

Use the following links to learn how to check your quota.

You may need to follow instructions OWA Premium not accessible from IE 11 to make OWA Premium (not light) accessible from Internet Explorer 11. There's no way to check quota with OWA light.
  • Outlook Web Access (OWA) Light: There is currently no way to check your quota with this program.
  • Apple Mail: Unfortunately, you cannot check your exchange quota from Apple Mail. We recommend using Outlook Web Access for this task.

    Both in Outlook 2016 and Outlook Web Access, the maximum mailbox size listed is 25 GB, while here it's listed as 15 GB. Is this article out of date where it says 15GB, or is there some kind of limit that kicks in at 15 GB even though that's not shown in Outlook or OWA? Thanks.

    The link for OWA Premium goes to a page that's about Outlook, not OWA.
