Office 365 service accounts are intended to be used for shared/changing roles (e.g., info, secretary, webmaster, newsletter, feedback, etc.) or service/programmatic access (e.g., printers, copiers, mailers). Service accounts can be accessed via all Outlook clients. Learn more about the types of accounts available within Office 365.

A sub-domain is a domain that is part of a larger domain; the only domain that is not also a sub-domain is the root domain. For example, doit.wisc.edu and engr.wisc.edu are sub-domains of the wisc.edu domain.
