My WIN 7 PC now sees all files with File Explorer without any fancy. Finally I found there are three elements to the problem, maybe what I found may help others.
My Office 2013 installation at home lets me add all 5 SkyDrive accounts. When I click Account - Add a service - Storage, SkyDrive is missing. Microsoft Office: Add SkyDrive account Missing from Office 2013 I have one SkyDrive account connected to my Office 2013 installation.Search for Ms office and click on uninstall, If you want you can try repair also but mostly repairing the ms office won’t the fix the issue. Method 1: Reinstall Microsoft Office Open Run command and type appwiz.cpl and hit enter.To narrow down this issue, try to remove all clients from this mailbox, and leave OWA only. It seems strange if the disappear message is irregularity. Every x number of emails disappears completely from Outlook.
