I no longer have the issue, all 5 computers' OneDrive are stable and have been for some time. They have the latest Windows updates as well as Malwarebytes updates. I have no exclusions set because I did not want to put a bandaid on the issue, especially
since we did not know if it worked or not.
I strongly suggest making sure your Windows is fully updated, as well as you antivirus and if you have Malwarebytes, then that as well.
Good luck.
My Windows 10 and MalWarebytes are both up to date on 3 computers. The one I keep having trouble with is a new (9 month old) Dell Inspiron that has Windows 10 installed on a 128GB SSD C: drive and most programs and data on the D: drive. The other 2 laptops
are older Dell Latitudes, one with a 256GB SSD C: drive (only one drive), the other has a 500GB 7200 RPM C: drive (only one drive). I wonder if the 2 drive config is the gremlin? Another older Windows 7 Dell Latitude has no problems nor does a 3 year old Windows
10 HP Pavillion (one drive).
