A couple of you have asked this question is different forms. Someone recently posted a comment asking whether they need a CAL to access TFS if they have MS Project. Here are some pointers:

If you have (Project Pro) AND (Visual Studio Team Edition or Team Suite), you DO NOT need an additional CAL to access TFS via Project Pro.

If you do not have (Visual Studio Team Edition or Team Suite), YOU NEED an additional CAL to access TFS.

Note: Project Pro integrates with TFS, Project Std does not.

If you are a project manager who does not have/does not need Visual Studio Team Edition/Team Suite, you can simply buy a CAL to access TFS via Project Pro or Excel. If you are a project manager who also has Visual Studio Team Edition or Team Suite, you do not need an additional CAL for yourself.

If you have Visual Studio 2005 Professional, you NEED an additional CAL to access TFS.

The retail price for a CAL is approx $500. Govt customers, as well as volume licence customers, can expect to get a 25-30% discount (depending on your agreement).

Hope I have added clarity and not confusion to the current state of affairs.
