Frequently Asked Questions

What is my Exchange quota?

A quota limits how much disk space is available for you to store Exchange data, such as your e-mail and calendar.

Every Exchange user has a 25GB quota.

How can I find out how much of my quota I'm using?

In Outlook Web App, hover over the name of your mailbox and your current mailbox size and quota displays.

See one these docs for the answer, depending on your Exchange client:

How can I control my quota?

ITS Exchange delivers two separate services - email and calendaring for users with sensitive research data and Voicemail. Determine which mailbox is over the quota.

Tips to control the mailbox size.

What happens if I reach my quota?

When you are within 1% of your quota, you will receive a warning message. For example, for the basic 500MB quota, you will receive a warning when you have used 450MB.

If you reach 99% of your quota, you'll receive a daily warning message until you reduce your account's size.

Should you exceed your quota, you will not be able to send e-mail until you have removed enough messages to get below your quota. You will, however, continue to receive mail, but you will not be able to respond or create new messages.
