Not the best of all options but if it is an Appvolumes message and it does not affect user experience just add this key
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\svservice\Parameters\HidePopups=1 (REG_DWORD value).
This hides all popups you receive from Appvolumes.
To fix this i had to delete the svoffice.xml file and it resolved the issue
Im having this same issue. Where exactly did you delete the svoffice.xml file from?
I was looking in the wrong place. I see its part of the writable volume configuration.
