Lost whole data from onedrive.live.com
I had uploaded my laptop data to my one drive account on 9th April 2022. I had to return my old laptop so i though to store word ,excel and some more documents on one drive. i uploaded data successfully on one drive. but yesterday(8th May) when I opened my one drive account again in my new laptop, whole data was lost. account was looking like a new account. There was not even a single data. Even I didn't receive any email about deletion of data. Please help me .How can I retrieve data again. those were my effort of many years .
