Can't connect to Exchange Server SMTP

[lauren@paradisepartners]

Hello,

 

I'm trying to set up the Email Plugin with an Exchange Server. I'm able to connect via IMAP, but not able to make an SMTP connection. I've added the "ssl=1" parameter (the server administrator says it is using TLS encryption), and have specified the port in the server address.

 

When using all the same settings in an email client, I am able to connect.

 

Is there something I'm missing? Will this not work with Exchange?

 

Thanks,

Lauren
