Let me run that by the report thread which had evidence that it is new. Nobody else has commented yet one way or the other. Not sure if this will need account access or a custom build of some sort to figure out what’s up. The easiest first step is probably to retest 2.0.4.35, because there’s probably at least a small chance of timing coincidences against change at Microsoft. How do we resolve this? First, perhaps ask for more details about SharePoint because it has so many forms (and I’m not an expert). Is this cloud-based Sharepoint, maybe as part of OneDrive for Business as was [mentioned in 2018](https://forum.duplicati.com/t/can-t-connect-to-onedrive-business-since-a-few-days/3154/6) (or maybe [Office 365 Business](https://products.office.com/en-us/business/small-business-solutions))? I don’t know if a test account is possible… Alternatively, test builds might be possible, but there are no official nightly builds. Canary is as needed. This would be a good issue to clear up soon, because it may be the final block to going towards Beta… --- _[View the full topic](https://forum.duplicati.com/t/bad-request-error-from-request-nameconflictbehavior-must-be-fail-replace-or-rename/8578)._
