Do you need to have full control permission on the site when creating an OAuth trust connection with SharePoint?

I have created an Office Outlook Mail app which authenticates to save emails to SharePoint using OAuth.  It's like a low trust external web server that request access to SharePoint on the fly.  It all works when the user has full control of the site, but when the user is only given contribute or edit permission, the trust dialog does not appear, it basically shows a blank screen.  The OAuth scope is List.Write.  Is there any way to allow for OAuth to a SharePoint site when the user has only edit /contribute permsssions on the site?
