I have the following to mention about changing the name of a custom list for SharePoint 2013.
1. In my test SharePoint area the person that is our 'admin' for SharePoint, went to the 'recent' area of my test area in quick launch and changed the name of my Custom list. The features like email messages did not work at the point.
2. I then went to list settings on the test website, and changed the name of the custom list to match the name my 'SharePoint' admin changed the name to. I reran my test workflow, and the features started to work again like the email messages.
**Note: Myself and the SharePoint 'admin' person at my company have only worked with sharepoint 2013 for 3 weeks.
Thus can you tell me relationship of changing the name of the custom list in the 'quick launch' area versus changing the name is the list settings? Do both areas need the values changed?
