E-mail Usage Limits & Checking Your Usage

Since the migration to Microsoft Office 365, email limits have changed. The new email quota is now 50GB for students, faculty, and staff. This is a significant increase over the previous limit of 1GB. You can check your current mailbox size from the Outlook desktop client or Outlook Web App. Mailbox usage will be displayed in megabytes (MB) or gigabytes (GB) depending on the size of your mailbox. Approximately 1,000 MB is equal to 1 GB.
