Microsoft Outlook Email outlook image

All email lives in the cloud at Microsoft 365 and is accessible from any device, anywhere. Benefits of using Outlook include increased mailbox sizes limits up to 50GB, online archive to store old email up to 100GB, capability to send attachments up to 25MB and unlimited storage in the public cloud. 

Microsoft Outlook is the only university-supported email client and is highly recommended for accessing your University of Colorado Denver | Anschutz Medical Campus email. In addition, OIT recommends installing the O365 Outlook app on your mobile device from the iOS and Android App store. Once you add the Outlook app to your phone, you can go to Settings and add other personal accounts such as Gmail.

MFA and Microsoft Outlook

DuoThe university now uses Duo Security to provide multi-factor authentication before accessing Outlook. Use the Microsoft Outlook desktop or mobile application for easiest access to your email. If you are accessing Outlook from on-campus, off-campus or your mobile phone, you will be prompted for MFA through Duo about every 90 days as long as you are using the Outlook application.

Please note: If you use a web browser such as Chrome or Internet Explorer to access web mail, instead of the Outlook application, you will be challenged for MFA every time you open a new browser session. For convenience, OIT suggests installing the Outlook application on your mobile and personal devices so you're only prompted to authenticate about every 90 days.
