Dear Sky (first, thanks for taking over Tisky's on this issue!)
As I mentioned before, earlier we have tried unlinking the PC, repairing/reinstalling/resetting OneDrive (I have the latest version, 17.3.7294.0108), and the other options you mention. This resulted in me having to re-sync hundreds of GBs of data which took
several weeks during which my professional work was seriously impeded.
I have also posted on social.technet.microsoft with all the details since I have seen elsewhere that advanced issues should be reported here: https://social.technet.microsoft.com/Forums/sharepoint/en-US/30f4a73d-515c-48e4-adc3-997bcc4f6132/office-applications-attempt-to-save-to-sharepoint-instead-of-local-drive?forum=sharepointgeneral.
Unfortunately, the conclusion was to open a ticket since the issue is complicated.
Yet, the engineer I spoke to for my first ticket said he could not help me since I have OneDrive for Business and they only help regular OneDrive users at this section. The engineer I spoke to for the OneDrive for Business ticket says he cannot help either
if this is a by-design, built-in feature, only if it is a bug. And he insists it is a voluntary addition from Microsoft, not a bug. So he says he cannot help. He says I would have to add a suggestion at https://onedrive.uservoice.com and wait until enough
people upvote my suggestion and hope that the development team will see it and decide to work on this, although this is far from guaranteed.
Can you see how this is a ridiculous loophole? Please provide another solution. Best.
PS:
Jeff Pollard: Thanks for the proposed workaround! (And for identifying the specific replication conditions!). I don't want to try it now in case I need to readily demonstrate the problem with other Microsoft engineers but I will keep this in
mind if no formal fixes are proposed!
TubaOrNotTuba: Thanks for expressing better than I can our common frustration and Microsoft's pure and simple denial of the existence of this problem currently. And thanks for your efforts with your ticket and the troubleshooting team too.
All: I just want to say thanks all for your support, Bob McKinnon, Alec Webster, Clofff, Jeff Pollard, Clifford Boobyer, TubaOrNotTuba, and Aapo Kuusela. Thanks for sticking together for this issue, hoping Microsoft will provide a workable
solution ASAP.
