Modification loss in excel files hosted on OneDrive
On December 4th I discovered losses of modifications in some files. When opening an Excel file I often work with, I was suprised since I was sure I added some lines into it a few days ago. I looked at version history and found a strange behaviour on December 4th: several versions on 29th November 15:06 with the same size. One of the 3 versions of 29th November 15:06 seem to be the latest in terms of modifications, even the size was similar. So I manually recovered this one. I did the same on a 2nd excel file to confirm the issue. Other files may be impacted. How can that happen? Could it be a ntp issue leading OneDrive not to know which version is the latest? I opened a case at MS support, but they closed the case w/o resolution. They even didn't try to understand the issue, just sending a TN how to restore a version of a file. But first I need to identify all the impacted files, then to find the correct version. I can't do these actions manually on hundred or maybe thousands of files. How could I proceed? Do u think it is related to Excel or OneDrive or to sthg else?
