With the implementation of Office 365 Microsoft Exchange email and calendaring solution, faculty and staff are encouraged to utilize the campus service for all university-related work instead of other third-party providers such as Hotmail, Yahoo or Gmail. However, if faculty or staff members determine that use of the CU Boulder email service interferes with their ability to pursue their academic or research activities, they can request an exception.

If you are associated with one of these organizations or national labs and wish to have your CU email delivered there, you will need to update your email delivery location in CU Boulder Identity Manager. Instructions for updating your email delivery location are available at Identity Manager - Email Delivery Location .

If an individual from an institute or national lab is seeking an exception, the individual should first contact their director or department chair to seek their approval. Then, the director or department chair should contact CU Boulder Legal Counsel, who will review the request.

If you feel that using any CU email account is unacceptable in fulfilling your teaching, research, or administrative duties, please contact your director or department chair. If after discussing the problem with your director or department chair you both feel that using a CU email account is unacceptable, complete the certificate of receipt with signatures from you and your director or department chair, and send, via campus mail to IT Security, 455 UCB, faxed to (303) 735-5036, or emailed to security@colorado.edu . IT Security will work with OIT Operations to have any email that is sent to your @colorado.edu account sent to the third-party address you specify.
