Exception (0x81071003): Unable to update the information in the Microsoft Office document

When adding a document (Excel) to SharePoint I get the exception: "(0x81071003): Unable to update the information in the Microsoft Office document".

The exception occur in a ItemAdded event handler where I add a global unique human-readable document id to the document.

This most likely due to an error in the property promotion/demotion part of SharePoint.

If I try to open up the Excel sheet myself I get an error as inline VBA code cannot be executed. So if SharePoint tries the same no wonder it doesn't work. But how can you block promotion/demotion in such situations.

Ideas very much appreciated.

Office property promotion/demotion in SharePoint

I came across this posting today about Office property promotion/demotion. Figuring out why and when properties are synchronized from SharePoint into Office and vice versa is quite a challenge. I'm still figuring out the details. Documentation and details needed.
