For most of our CIRES employees, you are allocated a CU Email (@colorado.edu) and, depending on your affiliation, an @noaa.gov email. However, some employees that were provided with an @noaa.gov email were never provided with an @colorado.edu mailbox and have all of their messages are forwarded to their @noaa.gov email. This guide will help you determine if you have a valid @colorado.edu mailbox and how to request one if one does not exist.

Step 1 - Login to Office365

Browse  to  https://office365.colorado.edu, enter your identikey@colorado.edu, click Next, enter your IdentiKey password and click Sign in. 

Step 2 - Open App Drawer

 Click on app drawer in the top left corner (grid of nine dots)

Step 3 - Find Outlook App

Look for the Outlook icon under the Apps section. If you see it then you were provisioned an office 365 mailbox, and by clicking on the Outlook icon you can see your @colorado.edu email directly in your browser.

If you don't see an outlook icon, you were not provisioned a @colorado.edu email box and one will have to be created. To have this mailbox created please call 303-735-4357 (5-HELP) or oithelp@colorado.edu asking for your mailbox to be provisioned and please be sure to provide your Identikey username.

Missing Email / Redirection Issues

If you are able to open Outlook but you don't see any email in your @colorado.edu mailbox, this most likely means that your email is being forwarded. You can turn off email forwarding by logging in to https://identikey.colorado.edu, clicking Manage My Email and Calendar Services and Changing your Email and Calendar Service to Office365.

If this tool does not work or throws an error please call 303-735-4357 (5-HELP) or oithelp@colorado.edu asking for your forwarding to be turned off.

Hidden Forwarding

In some cases there are redirects behind the scenes that can only be removed by OIT. If you are still having issues with your email redirecting, please contact CIRES IT (ciresithelp@colorado.edu) and our team can assist you with getting the redirect identified and removed.
