Office 365/Exchange

Overview

University of Colorado Boulder presented a lightning talk at 2015 Internet2 Technology Exchange on Grouper and Exchange / Office 365. See slides here (PDF format)

CU Boulder migrated from on-premise Exchange to Office 365 (O365) in June 2015. Here is a quick overview of the Active Directory environment relevant to Exchange and groups:

• The Office of Information Technology's (OIT) Identity and Access Management (IAM) team has the Active Directory (AD) domain and enterprise admin rights
• IAM creates top level OU's for the departments, schools, and colleges and delegates the full administration of these OU's to personnel (OU Admins) within these departments, schools and colleges.
• OIT's Messaging and Collaboration team (M&C) managed the on-premise Exchange infrastructure and the creation of the mail distribution lists.
• Many of the mail distribution lists were being used as security/access groups in AD
• DirSync was going to be used to sync accounts and distribution lists from our AD to the Azure Active Directory which introduced mainly the following issue:
  • Because it is a one-way sync, end users lose the ability to manage their distribution lists using Microsoft's Outlook or Outlook Web Access .
