OK...So I am on day 3 of this issue, and haven't solved it yet....and it's so frustrating....I have read article after article, and made change after change and still it doesn't work
I have turned off firewalls, I have telneted from internally, and externally, and it all seems to work.
I made adjustments to Registry and ensured Valid Ports are setup....which on a side note.....it keeps populating the Validports Registry Key with Old server information....I adjusted it to the new settings.....yet after 5 minutes the old setting showed up again....Does anyone one know where it was getting the information from?
I have been on this for a days and I am getting flustered. I have NOT configured Autodiscovery as of yet.... doing one thing at a time.
Included is the Remote Connectivity Analyzer report. Any help would be appreciated!!!!!!!!!!

Exchange System Attendant will populate the registry value "validports" with information dependant on your Exchange configuration. There is no need to manually edit this value since it wil be overwritten as you already noticed.
You probably have an older server in AD not being uninstalled properly.
