Hello all!
I recently discovered that even on admin role - I haven't been able to remove a user from our ArcGIS Online site that is from a different org.
The short version - we typically don't allow outside or third party users to access (editing projects) to our institution's ArcGIS Online site. But we had a user that figure out to add a participant from another school that has ArcGIS Online. So since both institutions have ArcGIS Online, they were able to add the user without having to use our typical notification/approval process.
I made adjustments to the permissions so now that can't be done anymore - but I found out that the user added data/files/projects to our site and I can't transfer ownership, delete the materials, or remove the user. Ownership settings aren't available and the delete settings are not available. They also appear to have access to our ArcGIS Pro licenses as well.
Has anyone else had this problem? I spoke with tech support on it, and they didn't have any answers for the issue other than updating the permissions - but no suggestions on how to remove the user from our system.
Thanks for the help!
