We have to upload about 50000 documents as attachments to items in a list (2-10 attachments per item). Requirements are: - We are not allowed to use Powershell. - We have tried to use CSOM, but site is using ADFS and we have problems with authorization in CSOM to connect to the site.
- Is there a better approach?
Which would be the better system for uploading documents to document library (we are thingking in OneDrive client, which synchronizes with document library, but it has a 5000 elements limitation):
Thanks in advance.
