I am getting an error when trying to sync some calendars with Outlook. The error is
"Task 'SharePoint' reported error (0x80070005): 'You do not have permission to view this SharePoint List (Site Name - Calendar Name). Contact the SharePoint site administrator. HTTP 302'"
This error is intermittent (removing the calendar from Outlook and re-syncing it sometimes resolves it temporarily) and does not effect all users at the same time. I have full control of the site as well as the calendar in question. I have tried breaking permission inheritance and setting unique permissions on the calendar with no change. I have checked AAM and all is correct (site is accessed the via the same URL internally and externally)
Our site uses both Forms Based Authentication and Windows Authentication. This issue is experience by users using AD (have not tried any FBA users).
