No... It's really an informational message letting you know that the Exchange Connector (BES component) is using the default communication information. Nothing to be concerned about. Although I wish RIM would stop logging informational things as warnings.
Thank you for your response. I was hoping that was the case. When you see the word "Default" used in a message like this, it makes you think that everything is probably ok, but like you said, they then turn around and classify it as a Warning. Go figure!
