we had a working connection with Windows live 2009 and 2012 to our exchange server until last week.
"Your server has unexpectedly terminated the connection. Possible causes for this include server problems, network problems, or a long period of inactivity."
The Microsoft Connectivity tool (https://testconnectivity.microsoft.com/
) does not turn up or show any errors to our Exchange server for IMAP connections. maybe a client or server side windows update has screwed this up? any help appreciated,
