I have setup incoming Email on my first WEF and it looks like it is working OK and I don't see any error messages. However, I have added a second WEF and I see error messages in Event Logs on the second WEF about incoming email. A critical error occurred while processing the incoming e-mail drop folder . The error was: Value cannot be null.
I am guessing it has got to do with the drop folder. The drop folder on the first WEF which the SMTP Service is running is poiting to the C drive. Is it because the second WEF doesn't have access to that foler? if so, what is the best way to set it up?
