During Live Mesh setup, you get the option to specify a username and then, choose"other e-mail address". I never saw a place to specify the email address. The username line will accept the ampersand so you can't put the email address there.
I have Live Mesh set up on my desktop using a comcast.net address. Is there some way I could use the same address for Live Mesh Mobile?
You *have* to use the same address on the mobile client as on the desktop for both to be in the same Mesh. Where does the ampersand come into play? The email address used to set up devices in Live Mesh is your LiveID. Since it works on the desktop PC, adding a mobile device to the Mesh involves installing the client and signing in with the same LiveID. -steve~ Microsoft MVP Windows Live ~ Windows Live OneCare| Live Mesh|MS Security Essentials Forums Moderator ~
