Shared Office 365 Email Folders and Permission Levels


Those who oversee email accounts in Office 365 can grant read access to others. This grants them the ability to see the contents of designated areas. With Shared Mailbox accounts, permissions must be granted by the Full Access Delegate over the account. Full Access Delegate permission is assigned by ITS System Administrators. With personal accounts, the owner of the account can grant access directly to others.

The links on this page show how Full Access Delegates and personal account owners can grant folder access to others, and how those with whom access has been granted can access those areas.

How to share or access shared folders:

Please follow the appropriate links for the methods used to access Office 365 by both the person sharing and the person accessing the shared areas:
