Regarding the error code 80070005-508-80070005-560, its occurs when offline Outlook Data File (.ost) is corrupted. This happens when Outlook is in Cached Exchange Mode and face problems on caching files on the computer. The solution is to re-create ost file. Another common issue with permission of folder and synchronisation is often caused by a folder or calendar that has been shared with you. The permissions are set to “Reviewer Rights” and you have Outlook setup in Cached-Mode. This causes the error because it’s trying to download the object without the proper permissions.
