Hi Dina 

Thanks for posting in the Lucidchart Community! Unfortunately Lucidchart does not currently support email notifications of updates to Team Folders. However we're always looking for ways to improve Lucidchart and your feedback is the best way for us to do that. Would you mind adding your idea to our feature request form? Ideas submitted to this form are passed on to the product development team for their consideration.

If you would like to learn more about the features of Team Folders take a look at this article from the Lucidchart Help Center and let me know if you have any further questions!
