I'm trying to view contact of the portal user from the user object in sandbox, but can't view it and I get the following error:
You do not have the level of access necessary to perform the operation you requested. Please contact the owner of the record or your administrator if access is necessary.
I have checked all security settings, sharing settings, permission sets, profiles, organization-wide defaults ...every thing seems to be clear. I have tried all but couldn't find a solution, it will be great if someone helps me out with this.
FYI I am using the Overage high volume customer portal profile.
