Hi everyone,
I noticed that in an onedrive business account it is not possible to deactivate the archiving of previous versions of a file if this is modified or overwritten. This puts in serious difficulty the available space (in my case 1tb) that after some time without adding so many files I have seen it shrink almost to the limit. Investigating the situation a little more I realized that many files (compared to the versions I have locally) took up almost double. The problem is that a copy of the file is created in the previous version. I contacted support and they confirmed that it is NOT possible to disable versioning. The only workaround is to delete the entire folder and upload the files again, freeing up a lot of unnecessarily (in my case) occupied space. Until the next time of course ..
Any tip is welcome.
Ale
