Email Quota

The amount of email and attachments that you have stored on the email server are subject to a quota amount. The quota for faculty/staff 2 GB. Messages (to include messages that you have sent) and attachments contribute to your quota size. The maximum size for a single email message (for both sending and receiving) is 20 MB.

To view your quota in OWA:

• Select the gear icon in the top right
• Select Options
• Select Account from the menu on the left
• View your quota status in the main panel

Following are the extensions blocked from being sent through our e-mail systems. If you need to email an attachment with one of the following extensions, you can replace the actual extension with ".txt". You should include instructions in your email telling the recipient to replace the .txt extension with the true extension so they can open the attachment.
