UMail was retired in early 2020 as it reached end-of-life, and is no longer supported. Faculty and staff using UMail received additional information about migrations to Google Mail and Microsoft Exchange.

This chart compares the features of Google Workspace: Google Mail & Calendar, Microsoft Exchange email & calendaring, and UMail as of April 11, 2019.

Apps include email, calendaring, and contacts. Information is hosted ‘in the cloud,’ on Google servers.

  • Access for mobile devices
  • Centralized address book
  • Email search function
  • File backups & data recovery

  • Out of office/vacation reply
  • Spam filtering
  • Subsidiary accounts (secondary accounts for projects, collaborations, student workers)
