Opening a shared task folder from another Outlook user's task folders.

You cannot open a shared Outlook folder from a sharing invitation that you receive from another Outlook user: Method 2: Open nondefault Outlook folders
You can view the nondefault Outlook folders just as easily as you can view the default Outlook folders. If you are invited to view a nondefault folder, the words "Microsoft Exchange" will not appear before the folder name in the sharing invitation.

To open a nondefault Outlook folder, follow these steps:

1. In Outlook, click E-mail Accounts on the Tools menu.
2. In the E-mail Accounts dialog box, click View or change existing e-mail accounts, and then click Next.
3. Click your Exchange Server account, and then click Change.
4. Click More Settings.
5. In the Microsoft Exchange Server dialog box, click the Advanced tab, and then click Add.
6. In the Add Mailbox dialog box, type the name of the owner of the shared folder, and then click OK.
7. Click OK, click Next, and then click Finish.
8. In the navigation pane, expand Mailbox - UserNameOfFolderOwner, and then click the folder that the user shared to you.

If you receive an error message or cannot open the shared folder after you follow these steps, contact the sender of the sharing invitation to make sure that you have at least the Reviewer permissions to the sender’s shared mailbox on Exchange Server.

To give you the Reviewer permissions to the shared mailbox, the owner of the shared folder can follow these steps:

1. Follow the appropriate steps:
   • In Outlook 2007, right-click Mailbox - UserName, and then click Change Sharing Permissions.
   • In Outlook 2010, right-click your email address at the top of the folder list, and then click Folder Permissions.
2. Click the Permissions tab, and then click Add.
3. In the Add Users dialog box, specify the user to whom you want to share the folder, click Add, and then click OK.
4. In the Name list, click the name of the user whom you added, click Reviewer in the Permission Level box, and then click OK.
