CALS O365 - Using Office 365 Service Accounts

Accessing and using O365 service accounts

CALS Administrative Computing Services (ACS) will create service accounts for CALS Administration staff usage as requested.   These will be separate email accounts serving a specific need or role.   By default, those staff that have been approved to access the service account will have their netids "linked" to the O365 service account enabling easy access through the web client (Outlook on the web/OWA).   In addition, most service accounts will be "searchable" in the O365 Global Address List (GAL). 

Service accounts will be "web-enabled" which will create account credentials (username/password) and allow the account to be used for some netid-based applications.
