Email features

  • 15GB mail quotas
  • Outlook Web Access client provides convenient access to email.
  • Improved ability to manage emails subject to retention policies.
  • Reduced need to use PST files for archiving email. By moving the contents of your PSTs back into your mailbox, you can browse or search for those items through OWA.
  • Enhanced Out of Office Assistant. You can set an auto-reply message for senders outside of UM that is separate from the one seen by senders within UM.
  • Conversation view (available in OWA as well as the desktop client) enables you to quickly identify the most recent messages in a chain of grouped messages and responses, even when messages are located in different folders. A conversation of grouped messages can be managed as a whole.

Email Client Configuration

Outlook clients will attempt to auto-discover and configure the correct settings for your ssoid@umsystem.edu account.
