Yesterday evening, my boss sent me an email complaining about problems mapping network drives (Server 2008r2) and connecting to the office LAN after setting up offline files. He tried troubleshooting to no avail. I suggested SFC.exe and/or a systems restore. However neither one worked.
System restore failed to extract file C:\Users\...\local\Packages\microsoft.windowscommunicationsapps_8v from the restore point.
Unspecified error (0x8007045b)
SFC.exe /scannow does report that it found errors, but could not fix them. I have a CBS.log file that I could post somewhere...
All this on a Surface Pro 3 running Windows 8.1
