Office 365 - Why does UW-Madison need to maintain some local infrastructure for email and calendar after the transition?
Keeping some local infrastructure in place after the move to Office 365 allows campus to maintain several advanced, but widely used email and calendar functions that are not available through Office 365 alone. These functions include:
IP-based unauthenticated sending (used for copiers, servers, etc)
Advanced mail routing used by lists and other services
Advanced mail routing to maintain deliverability for all current addresses
Mass mailing that exceeds the limits of Office 365
Enhanced antivirus and spam filtering capabilities
Calendar tools - importing of student class schedules
Customized delegated administration functions
Maintaining some local infrastructure allows us to continue to provide these services, which will minimize disruption to campus.
