OneDrive seems to be syncing all files except Excel files. I will work on a Excel file with a desktop computer and then save the file. I check the OneDrive icon and it shows all files up to date.

I then go to my laptop and open explorer and find the same file I was just working on with the laptop. I can see the Date and Time are stamped with the exact time I saved it. However when I open the file on the laptop, none of the changes are there. The file contains the information that was in the file the last time it was saved on the laptop.

If I make changes on the file in the laptop and save it back to OneDrive, those changes are visible on the desk top when I open the file. It makes no sense. How can the date and time of the file be the date and time the files was saved on the desktop but the file has the information from the last time it was saved on the laptop.

I have reset OneDrive on both computers at least 5 times. This just started last night after working for almost a year. I can find no information on how to fix this issue.

Desk top runs Windows 7 Professional and Laptop uses Windows 8.1. Both computers using Office 365 Premium.

Microsoft apparently has eliminated CHAT support. I am at a loss how to try and fix this issue.

Its different problem if all files other type like pictures, docx are sync normally and only excel files not able to sync.

You can follow these task. May be your file corrupted so unable to sync. Just copy your file and login to onedrive.live.com here you can upload your file on specific folder and check back on PC that uploaded file sync on PC or not.

If your excel file sync on local now then make a new file on one drive folder on local and save data on it. Hope it will be work

If uploaded file on one drive is not able to sync on local machine then you need to fully install again Microsoft office 365 and one drive again. Hope it will be work

I have the same issue and the suggestion of a corrupt file although fair is just not the case.  It shows when looking on my local machine File Explorer but does not show up in OneDrive via the browser. 

When you right click on the file in File Explorer the OneDrive for Business menu item is greyed out.  The only way I have found to fix when this occurs is a workaround, not a solution, to go online and manually upload the file and it works fine after that.

Quick update to what I wrote above, I found another link talking how to repair syncing via right click on taskbar icon and clicking repair.  It found the missing file and synchronized it.  So now I am convinced the file is not corrupt, something in the process is.  I am happy to have a slightly faster fix (make sure to close the file and program using the file as it still will have remnants of the file considered open) before repair) but not happy I even have to do this to begin with.
