I will see...
The Core_FTP setup is kind of in a Black Box and I dont have access to it... I'll see if its logging anything....
I'll at least post the logs from WinSCP...

If you can login with Core FTP and not with WinSCP with the same setup, please post log files from both.

I have tried a number of different options.... So far the "this looks closest" result is...

• FTP
  
• TLS/SSL Implicit encryption...
  

This way I get a connection and then Access Denied...
Pretty sure I have the right password, but I am going to check with both the Client and with Open Text (We have two Mailboxes with Open Text... No issue connecting to the second...)
The Second is using SFTP
(
File transfer protocol = SFTP-3
Cryptographic protocol = SSH-2
SSH implementation = APACHE-SSHD-2.12.0
Encryption algorithm = AES-256 SDCTR (AES-NI accelerated)
Compression = No
)

On the Login dialog, select "FTP" protocol. And I believe that the "SSL Direct" might be equivalent of "TLS/SSL Implicit Encryption" (if that does not work, try Explicit too). Change the default implicit port 990 to 6366 of your server.
And enter your hostname, username and password.

I have a configuration for Core FTP that has been working, but is kind of a Black Box... And doesnt seem to allow automation...

I want to adopt it in Win SCP.... But all my experiments do not connect...

Any ideas....
