Not that Microsoft wants you to know that. They make the offline account button/link smaller and harder to spot regularly. I've thought several times that they finally removed it only to spot it hiding in a corner in a grey link one shade darker than the background.
They could be treating it internally as unsupported workflow too. Or at least untested workflow. Kind of like that issue where your CPU would be loaded 100% when you open start menu if you have cortana disabled.
