Sharing lets you give others access to your mail folders. You specify which folder, and the level of access, that is, whether the delegate can simply see items in a folder, or whether they can create, edit, and/or delete items.

A few things to remember about subfolders:

• If you share a parent folder, and also want to share one or more of the subfolders, follow the same process as you must change the sharing permissions for each of the subfolders you want to share. 
• New subfolders (created after sharing rights were set) inherit the folder access permissions of the parent folder.

This example shares your Inbox, but you can share any of your mail folders on the Exchange server. (You cannot share a folder on your computer.)

1. In the Navigation Pane, right-click the folder you want to share. You can only share folders on the server. You cannot share a local folder.
2. From the dropdown menu that appears, select Sharing Permissions. A Folder Properties dialog box will open with the Permissions tab selected.
3. If the name of the person you’ll be sharing with is listed, skip down to step 7.
4. Click Add User.
5. In the field at the top of the Select User dialog box, type all or part of the person’s first or last name, then click Find. Accounts that match what you typed will be displayed.
6. Click on the person you want to share with, then click Add.
7. Back on the Folder Properties dialog box, click on the person’s name, then choose from the Permission Level dropdown list.
   •  If you just want to let this person read your messages, use Reviewer.
   •  If you want them to read AND be able to drop messages into a folder, use Non-editing Author.
8. Click OK.
