Can I limit member privileges of users from outside my organization?

PatrickFilyer

I have a few maps that I would like to share with members from outside of my organization on ArcGIS Online. Is it possible to limit their roles so they can't edit the data (i.e. view only)? are there any group membership roles I can use/create to achieve this?

Instead of limiting the users role, I would suggest limiting the editing capabilities of the layer using hosted layer views:

https://vdot.maps.arcgis.com/apps/Cascade/index.html?appid=84c75208e15e49e48ca2a05410996c7f 

This way you control how the content in your app is accessed by who the app is shared with instead of creating a custom role for each user that you must manage.  Build the app and layer with all the needed capabilities that the consumers. There is an edit privilege that can be applied to custom roles, but these do not apply to editable apps shared with everyone.
