Exchange Online gives users e-mail, calendar, and contact functions, plus built-in antivirus and antispam protection. Users can gain access to information by using Outlook on their own PC or Outlook Web Access on any Web-enabled device, or by using a smartphone or tablet.
To get to Exchange configuration settings, click Manage under 'Exchange Online' on the Office 365 Admin Overview page. The left pane has links for managing users and groups, roles and auditing, mail control, and phone and voice options. Within Users & Groups, the admin can edit the configuration of individual users' mailboxes, create or edit e-mail Distribution Groups, add External Contacts, and migrate e-mail to Exchange Online.
