cannot add exchange mail on Nexus S running 4.1.2
This is an issue of login name and server name.

After entering your email address and password. Don't click next, but click Manual Setup.

The next page should ask for your username, password(properly fill in for you already), and Exchange server.

Username: &lt;Windows Domain&gt;\&lt;Windows Login&gt;
Exchange Server: (you should know, or find out from your Outlook setting)


Good luck!
