I'm having problems downloading mail in Notes 8.5 - Gmail Help

To get IMAP for gmail working Notes I needed to run a telnet check. Not sure if this will be needed everytime or not.

I'm having problems downloading mail - Gmail Help: "To run the telnet test on a Windows computer:

1. Open the Start menu, and select Run.
2. Enter command in the Open: field, and click OK.
3. Enter 'telnet imap.gmail.com 993,' and hit Enter. (Does the information in the prompt window clear? If not, please note the message that appears.)
4. Close the prompt window."
