IMAP server closing connection

Hi all, this keeps happening:

Microsoft Office Outlook, Your IMAP server closed the connection. This can occur if you leave the connection idle for too long.

 

Courier-IMAP server shut down by signal.

                Protocol:              IMAP

                Server: imap.plus.net

                Port:      143

                Error Code:         0x800CCCDD

Any advice welcome as it's happening all too frequently now & is driving me to distraction. TIA

Re: IMAP server closing connection

For example see IMAP error code: 0x800CCCDD - Microsoft Community

The key piece of advice is to lengthen the server timeout period - 10 minutes is I think excessive, usually (if that's the problem) 2 or 3 minutes in place of the standard 60 seconds is usually helpful ... thought if there is a real problem it might lengthen the time it takes to get the real error report.
