Team Foundation Server Trial can be extended in the event that your trial period expires and you are in the process of purchasing a fully licensed version. In order to do this, you must contact your Microsoft sales representative. Your representative will ask you to give them the current trial ID listed below and will in turn give you a new trial ID that you can enter in the field at the bottom. This will extend your trial period by 30 days.
