When checking a document out from one of our document libraries, every once in a while it will not allow us to save the document indicating some fields have required properties, when in SharePoint the column settings for the Library have these columns set to not required or mandatory. This is causing an issue as we cannot save the document and when the customer tries to fix the issue they end up losing the changes they made because it ends up not saving the document.
We have a workaround in place to go into the document and set the values for these columns if needed and then save, but it does not always work.
This issue is hard to reproduce. I have only heard reports about it.
As explained by customer:
Issue: When checking out the document and opening the document "in app," a yellow bar pops up at the top that says that required server properties are missing and need to be corrected in order to save the document. All required fields are filled in as indicated by the red * items. In addition, this was crosschecked with the PolicyHub properties and the required fields are complete. When reviewing the Info, Advanced Properties, of the file in word, the following fields have red boxes around them, so it is indicating these fields have to have a value in them in order to save the document and check it back in: DocumentStatus, Approval Status, Approved By. Approval Status and Approved By should never be added manually. They should always be updated by a workflow. I tested one document and filled in the red boxes and it allowed me to save the document and check it back in, so for some reason it is making all the fields be required to save and check in, even if the fields are not required. I also reviewed the advanced library settings and ensured that those fields did not have required set to Yes, and confirmed they are set to No. We need to figure out why Microsoft Word is considering all blank fields to be required for save even when they are not required fields.
