Hello MarcLaflamme,
Not sure why you are just now seeing the message. Did you make any changes to your AEH( Automated Home Email) template? If so then that might have triggered it. If you would like you can pull some SPcollects from both SP’s I can review them to make sure it was just a test & not an failed SPS. I will create a dropbox that you can upload the logs to & send you an email with a link to upload the files.
Please let us know if you have any other questions.
