Have you tried running the Verify and Repair Project tools through Site Admin? - I did. Nothing found.
Was this project created originally in your current version of ALM, or an earlier version? - Earlier version and was upgraded.
Are you using the Project Template feature and is this project linked to a template? - No.
Thanks for your direction Trudy... I was looking around and found an entry '@RN_TEST_ID ' in the MAILCOND table of the project. Once I deleted that, I could access the Automail without seeing the error message.
Problem solved!
