I have read several forums and applied all the troubleshooting solutions: Correct passwords with the username by making sure I enter the full username email address. Nothing has worked. What I am uncertain about is the server response: account is locked by another session or for maintenance. try again. ????? What does that mean?  I need help here and cannot find any way to send/receive emails using WLM after trying everything I could find online about this problem. Any suggestions?
