This does retrieve the various contacts I have, but not the names of any contact lists or their members. The "count" of items that is retrieved does include those contact lists but not their actual data.
I have tried the "people" and "groups" endpoints but those retrieve different information, not what I am looking for.
I know I can use EWS for this purpose, and I have, but I'm trying to convert my existing application to 100% Graph. I would appreciate any information, thanks.
