There are red 'X's next to some of the skydrive directories. When I log into skydrive online it shows the name of the file but there is no data in the file its properties says 0KB. This has occurred with about 20 files. Why would skydrive show the file but only sync the name of the file and none of the content. This happens with all types of Office files not just docs. We just recently installed office 2013 with an exchange server account but and the user had a previous skydrive account. Would the exchange server account cause confliction and if so why did it only corrupt a select few files?
