Good day ts678,
I was able to get some numbers from one of the notebooks with the problem.
As far as I can see Duplicati reads the FreeQuotaSpace from somewhere with a wrong value as this user has lots of space available

Has used 3.14% out of 1 TB
These are the numbers.

The other notebook that I tested configuring to an external hard drive worked perfectly well, so from my point of view it has to be related to upload the backups to One Drive V2
Hope this can help
