I can't seem to modify the standard My Opportunities list view in our org. I was able to modify this view in my own developer org without any issues.
Some searching online showed that there are two permissions related to editing list views: Manage Public List View and Create and Customize List Views. I verified and both of these permissions are available to me on my profile (I'm using the standard admin profile).
The last modified user was an admin that is still active so I logged in as him and could not update the view. The creator was no longer active so I re-activated the user and try again, and still could not update the view.
The error I get is:
Validation Errors While Saving Record(s) There were custom validation error(s) encountered while saving the affected record(s). The first validation error encountered was "This View Unique Name already exists or has been previously used. Please choose a different name.".

Does anyone know what I need to do to enable this functionality? I know it can be done I just don't know what's stopping me from doing it.
