When another Microsoft Outlook user grants you permission to his or her Tasks folder, you can open it in Outlook. If you don’t have permission, a permission request email message is sent to the other person.
Note: A Microsoft Exchange Server account is required.
In Tasks, on the Folder tab, in the Share group, click Open Shared Tasks.
Type a name in the Name box, or click Name to select a name from the Address Book.
After you access a shared Tasks folder for the first time, the Tasks folder is added to the Navigation Pane. The next time that you want to view the shared Tasks folder, you can click it in the Navigation Pane, under Shared Tasks.
If the other person whose Tasks folder that you want to open hasn’t granted you permission to view it, Outlook prompts you to ask the person for the permission that you need. If you click Yes, a sharing request email message opens automatically. The message requests the person to share his or her Tasks folder with you and also provides the option to share your default Tasks folder with him or her.
You can open only the default Tasks folder. Even if a person has created an additional tasks folder, you can open only the default Tasks folder.
To remove a shared task folder, click the folder, and then on the Folder tab, in the Actions group, click Delete Folder.
The owner of the task items controls who can see the task items and change them.
