  2. Right-click on the folder you want to share.
  3. Click Share Folder. The Shared Properties dialog displays. Select whom to share with, e.g. Internal user
  4. Depending on with whom you share, you do the following:
    • For Internal users or groups, enter the email addresses and in the Role area select the access privileges.
    • For External guests, enter guest's addresses and the password to enter to view your mail folder.
    • For the Public, direct the public to the URL that displays in the URL area. For example, you could copy and email this URL to those you want to view the page.
  5. In the Message area select which type of message to send. This message can be sent to internal users and to external guests. The options are as follows:
    • Do not send mail about this share. No message is sent.
    • Send standard message. The standard share notification message is sent to the email address. This message includes the name of the mail folder that is being shared, your address, the grantee's address and the role assigned, with a list of the allowed actions.
    • Add a note to standard message. You can add additional information to the standard message.
    • Compose email in new window. Create and send a new email message.

Accepting an invitation to share a mail folder

If you receive an email notice that you have been granted access to share another person's mail folder, you can accept or decline the share.

You can accept a share using the web interface as follows:

  1. Login to the web interface at
  2. Click Accept Share in the email. The Accept Share dialog opens and describes the role granted to you.
  3. Before you accept, you can change the folder name and select a color to high-light the folder.
  4. (Optional) Select to send a confirmation back to the Grantor.
  5. Click Yes. The folder is added to the grantee’s Overview pane. The message is moved to your Trash folder.

You may be able to accept invitations to share mail folders directly in other mail clients too.

As an alternative to accepting an invitation to share directly from the email received you can also

  1. login to the web interface
  2. click on the preferences tab and look in the sharing section of the preferences.
  3. In the sharing preferences you can search from items shared by other users simply by entering their name (as you start to type a name it will offer you the names of people who match) in the box marked Show folders shared with me by the following user, ticking the button next to this option and pressing the find shares button.
