This Microsoft Answers reply describes a similar problem.
The "Check emails from other accounts" Gmail feature simply uses POP3 to get e-mails from other e-mail servers.
I've removed my Spectrum e-mail account from all clients/synchronizing services I can think of.
However, with correct credentials and POP3 server information (mail.twc.com:995 with SSL/TLS), I still get the error message
[IN-USE] account is locked by another session or for maintenance, try again.
In case I'm missing a client/service, is there a way to make the Spectrum account disconnect all of them?
Alternatively, can I get a list of all systems connecting to my Spectrum e-mail account?
