I have an excel sheet setup with 6 custom properties linked in the advanced properties section of the file to the SharePoint column Column names from named ranges in Excel. The first three properties work fine and appear in SharePoint as soon as the file is uploaded. However any further custom properties i add do not appear, regardless of which property i set i seem to be stuck at three. I have created new columns and links still does not work, these are text fields to single line of text in SharePoint.
Is there a hard limit of three properties if not how do i diagnose the issue as I can not find any information on error logs that may relate to this.
In the preview window for properties in Excel the values show correctly
Thanks, G
