Exchange 2007

Last Updated: 04/20/2015


CU-Boulder's Exchange service is designed to help faculty and staff collaborate more efficiently and effectively through a suite of services including email, campus-wide scheduling via the calendaring function, contact and directory data, task management and more.  Exchange provides ubiquitous access to these features through desktop programs, web browsers, and mobile devices such as SmartPhones.


Exchange Online migration

The migration of accounts from Exchange 2007 to Exchange Online is part of phase 2 of the Microsoft Office 365 project. Starting February 2015, campus units and departments began being migrated, on an individual basis. If your department has been migrated, please visit the Exchange Online service area for more information.

To assure the migration to Exchange Online is as seamless as possible and for the Office 365 project team to address migration issues.

  • Delegated Permissions: Users with delegated permissions to calendars or mailboxes must be in the same environment
  • Distribution Lists: Management of lists will change; Exchange Online does not allow management from within Microsoft Outlook.
  • Large Messages: Messages that are 75 MB or greater cannot be migrated to Exchange Online.
  • Email Program Issues: Some email clients (i.e. Apple Mail) do not automatically recognize and reattach when one's inbox is moved to Exchange Online.
  • Custom Address Lists: Office 365 supports custom address lists, but they work in a different manner than the current environment.
