You can grant access to or share one of your mail folders to other users. The user may then subscribe to that shared folder.
Right-click the folder you wish to share and select Properties.
The properties dialog for that folder appears.
Select the Permissions tab.
Within the Permissions tab:
If you know the userID of the person to which you want to share this folder, enter the userID and click Add. The specified userID appears in the list below.
If you do not know the userID, click Search to search your address book directory.
Select the userID (or anyone) from the list and choose the permission rights you wish to grant.
The available permission rights are:
Read and write
Read, write, and manage
You must select at least read only in order to share a folder with another user.
If you wish messages to be sent directly to this folder, enable the “Enable direct delivery of email to this folder” checkbox. This enables the ability to send email directly to this folder using the following syntax:
user part of email address + folder name @ domain part of email address
For example, if the checkbox is enabled in John Smith's engineering folder, anybody will be able to send a message to John using the address firstname.lastname@example.org. This message is delivered directly in the engineering folder. If the checkbox is not enabled, a message sent to such an address is delivered to John Smith's Inbox.
Click Apply to apply changes or OK to apply changes and exit the dialog.
