Regarding set-up of IMAP on exchange 2010 sp3, there are a couple of things I don't understand.
1) I have SSL v2 & v3 disabled on the server via registry. So how are clients able to connect to the exchange server on port 993 with SSL enabled? Is it actually falling back to no security or falling forward to TLS?
2) According to the below dialogue, TLS should use port 143, but also no encryption should use port 143. So which is it? Is it purely controlled by the next tab 'Authentication'?
3) With the IMAP receive connector shown below, does the 'Integrated Windows Authenication' also only operate after the TLS connection is established or does it work outside the TLS connection?
