How To Share Folders In Outlook 2013/2016 For Mac

There are two ways to share folders in Outlook 2011/2016 for Mac: by creating delegates (only for top-level folders), or by assigning sharing permissions to a folder (for both top-level folders and subfolders):

Note: Outlook for Mac only allows sharing folder with at least Reviewer permissions.

Sharing top-level folders by creating delegates

Using this method, you can add another user as a delegate, then specify which folders to share with this delegate and what level of permissions the user should have.

Note: Only top-level folders can be shared this way (Inbox, Calendars, Contacts, Tasks, Notes).

To create a delegate and share folders:

1. In Outlook Top menu navigate to Tools > Accounts > Advanced > Delegates.
2. Under 'Delegates who can act on my behalf', click on '+' (Add a delegate).
    
3. In the Select User window, start typing the user's email address and click on Find. Choose the mailbox from the list and click on OK.
    
4. In new window select delegated permissions for each of the top-level mailbox folders (Inbox, Calendars, Contacts, Tasks, Notes). The three levels of permissions that can be assigned to a delegate are:
   • Reviewer (can read items)
   • Author (can read and create items)
   • Editor (can read, create and modify items)
     
     Note: if you share calendar and check the box Delegate receives meeting invites, you delegate would get all your meeting-related notification to their Inbox.
5. Click on OK.
6. The delegate will now be able to open the selected folders in Outlook for Windows or Mac.

Sharing top-level folders by assigning sharing permissions

Note: Only top-level folders can be shared this way (Inbox, Calendars, Contacts, Tasks, Notes).

1. In Outlook, right-click on a folder that needs to be shared and choose Sharing Permissions.
    
2. On the Permissions tab:
   1. Click on Add User.
   2. In the Select User window, type the user's email address or select the user from the address book.
   3. Select the newly added user and assign permissions.
       
3. Click on OK.
4. The user will now be able to open the selected folders in Outlook for Windows or Mac
