Is there a way to set "work offline" in TFS without having to try opening a solution, waiting for it to time out, and then having Visual Studio work out that it has failed?
It seems a touch ridiculous that I can't just tick a box to tell it myself, seeing as I'm probably the one most qualified to know when I'm not in the office!
This extension should solve your problem (for VS 2010):
