Free/busy is a determination of whether there is a calendar event in a given time slot. Free designates time slots without events and busy designates time slots that are taken up in a person's calendar. Any account within Office 365 will have the ability to view free/busy information against any other Office 365 account.

Full mailbox permissions can be assigned between any two accounts within UW-Madison's Office 365 environment.

* To send emails, you will either need 'send as' or 'send on-behalf' of permissions.

Note: Service accounts have the capability of having delegates linked to them. If linking is used, the delegate will automatically be assigned 'full mailbox' and 'send as' permissions.

See how to manage full mailbox permissions for an account for further details.
