lms portal 1.0.1

So you have LMS 3.0.1. The Discovery settings can be changed under Common Services > Device and Credentials > Device Discovery > Discovery Settings. The email is found under Global Settings.

I confirmed that it has been changed but the person is not receiving any emails. The previous person that had there name is still receiving them.

Go to Discovery Schedule, and Delete all of the old Discovery jobs. Then create a new schedule based on the current settings. The new email addressed should then be used.

before deleting every discovery job check the settings for each job by clicking on "Edit Settings". Have a look if the email address was changed for the scheduled discovery jobs as well.

This option is not available in LMS 3.0.1. He will only be able to delete the old jobs, and schedule a new one.

that is what I did, deleted the old job and scheduled a new one to run this weekend.
