Dear @Jess Graham,
Thank you for posting your question in the Microsoft Q&A forum.
The following are some possible causes for this error:
- The Require Check Out option is enabled on the library.
- There are Required columns entries for the library.
- The Draft Item Security option is set to Only users who can edit items.
- You're syncing by using an external or guest account for OneDrive.
If the below steps require administrative rights, please reach out to your Global Admin or SharePoint Admin for assistance.
Help me navigate to your OneDrive URL > click settings icon > OneDrive Settings > More Settings > scroll down and click Return to old Site settings page. (Or you can go to your SharePoint site > Library tab > Library Settings > More Library settings)
Navigate to Site libraries and lists > go to customize documents > Versioning settings.
(Or you can go to your SharePoint site > Library tab > Library Settings > More Library settings > Versioning settings.)
Change Content Approval to No.
Draft Item Security to Any user who can read items.
Change Require Check Out from Yes to No.
Then save.
Apart from these three options, there is one more option. In customize documents page (or in Library settings) > check each column for a check mark under Required. For any columns that have the check mark, change the Require this column to contain information value to No.
Note: Syncing content by using a guest or external account is not supported. Instead, use an account that's internal to your organization.
