The following tutorial steps through the process of how to share an email folder as well as add a shared folder to your account within the Outlook Web App. These steps are the same for individual mail folders as well as shared mailboxes (e.g. department accounts).
Before email folders/mailboxes can be shared with other users on Office 365, you must set up the account's default folder permissions. If this step is not performed before sharing, the folders will remain inaccessible to those users.
Right click the folder or mailbox you wish to share and select Permissions...
It is good practice to send an email message to the account you just shared the folder with to inform that they now have access.
|Owner||Full rights to the folder, including assigning permissions to others|
|Publishing Editor||Create, read, edit, and delete all items, and create subfolders|
|Editor||Create, read, edit, and delete all items, and create subfolders|
|Publishing Author||Create and read items and subfolders, and edit and delete created items|
|Author||Create and read items, and edit and delete items you create|
|Non-editing Author||Create and read items, and delete items you create|
|Reviewer||Read items only|
|Contributor||Create items only (folder contents are not visible)|
|None||No permissions (you cannot open the folder)|
Shared folders must be manually added to your list of folders. There are no automatic notifications when a folder is shared, so it is important that the folder sharer let the recipient know about it.
