To check your quota before you're you're out of space, log into owa.mit.edu and move your mouse carefully over your name in the left column and wait 1-2 seconds. A yellow box with your current disk space quota usage should appear. If you accidentally move your mouse while the yellow box with your current usage is showing or accidentally click the mouse, the box will go away. To get it back, you will have to move your mouse away from your name about 3-5 seconds (sometimes you will need to click on a blank spot in the owa window to get it to "reset") and then move your mouse slowly back to your name and wait 1-2 seconds to get the yellow box showing your current disk quota usage to come back up.
IMPORTANT: If you max out your quota, you will not be able to send mail. Depending on how badly you're over your quota you may not be able to delete email either. Should you encounter this situation, you or your IT Tech liaison, or your AO will need to contact IS&T directly to have your quota increased either temporarily or permanently to fix this issue. Requests for permanent quota increases should ideally be made to IS&T by the AO or section heads.
Email sizes
There is a maximum email size of approximately 30MB per email. This assumes both sender and recipient are on the MIT Exchange email system.

Please note however that other email systems outside of MIT may have lower or higher limits depending on their system.
Calendaring
There are a number of preventative measures people who use the Exchange calendaring need to be aware of in order to keep your calendar happy.
