Work Offline when the Server is Unavailable
If the server that is running Visual Studio Team Foundation Server is offline, you can change local, offline copies of your files. After the server becomes available again, you can check the changes into version control.
To perform these procedures, you must have the Check out permission set to Allow. For more information, see Team Foundation Server Permissions.
