Hum. "Mailbox is in use" errors are returned by the mail server, and are indeed an error indication. BUT -- and this is important -- this is NOT an Evolution error.
Evolution is doing the right thing, it just happened the mail server decided it could not accept your login. Usually "mailbox in use" means you are already connected to the mail server, so this (new) session is rejected. I am personally inclined to close this bug invalid. I will also adjust the description. ** Summary changed: - Unable to connect to one account; -ERR in sending password, can't get lock. + Unable to connect to server: -ERR in sending password, can't get lock. Mailbox in use -- Unable to connect to server: -ERR in sending password, can't get lock.
