Hi @Alen.Alempijevic,
OneDrive for Business handles throttling strangely. Most providers (including standard OneDrive) primarily enforce limits on the user, and will throttle a particular user if they are exceeded user-based API limits. OD4B tends to throttle at the tenant and global level much more aggressively, so you will end up hitting these limits, even if you have not been using the service much.
In your case it seems to be more tenant-level. We have been working on ways to combat this to improve the user experience. We have some additional changes in the pipeline for this, too, which I’m hoping we can push out in the next week or two.
The OneDrive native clients seem to have higher thresholds than the limits they allow 3rd parties, like odrive, so you may not see the same behavior on their own clients.
How many users do you have in your organization?
