UMail account migration to Exchange Online starts on June 1

Prehead: Faculty and staff accounts are moving to Microsoft’s cloud server.

Starting Tuesday, June 1, 2021, University Information Technology (UIT) will begin to gradually migrate all University of Utah and University of Utah Health faculty and staff UMail accounts from Microsoft Exchange Server (hosted on campus) to Microsoft Exchange Online (hosted online by Microsoft infrastructure). The upgrade is part of the effort to modernize the U’s communication technology and better meet the needs of those working, learning, and teaching remotely.

Faculty and staff will receive a targeted email 24 to 48 hours prior to initiation of their account migration. The total time for your migration depends on the size of the mailbox(es) to be moved and amount of data to be transferred to Microsoft servers. Extremely large mailboxes can take a number of days to transfer.

If you’re unable to access your UMail account through your desktop/mobile client or web browser after the migration, please refer to this IT Knowledge Base article for instructions. Please note that UMail is always accessible via Outlook Web Access (OWA) using a web browser.

After your account moves to Exchange Online, you may receive a notification that says “The Microsoft Exchange Administrator has made a change that requires you to quit and restart Outlook.” Please follow the directions.

The migration includes an updated interface for OWA, which will redirect from to The interfaces of the Outlook desktop and mobile clients will remain the same for most users, although some macOS users may automatically update to the latest version of Outlook for Mac.

Other changes include:

  • Mailbox storage increased to 100GB
  • Retention of deleted items and off-site backups decreased from 90 days to 30 days


Until the entire university migrates to Exchange Online, you may experience some temporary UMail issues, including:

The upgrade has been approved by the university’s Strategic Information Technology Committee.
