Hi @onedrive,
I took a look at your diagnostic and noticed that you have several things listed in “not allowed”, which makes it a little difficult to determine what else is going on. It looks like most of the items that are in not allowed are due to characters in the file names.
We have a recent build which we haven’t officially released, but should soon, that removed the pre-check for the ‘+’ and ‘&’ characters. These used to cause problems with OneDrive for Business, but that behavior seems to have been corrected by Microsoft.
Can you install this build and see if we can clear out those items? This may also help with the issue you originally came in with: https://www.odrive.com/s/7a96e245-03a6-4988-9fcc-ac79b4721912-5aa72882
