My apologies for the delay in response, I have been traveling for work. We followed all of the tips provided including trying on google sheets as well as downloading LibreOffice. My IT rep made sure to do the UTF8 encoding as directed. Still, regardless, everytime we upload and map it says completed and when we go to the manage tab there are no entries. This used to work fine even just with excel CSV import.
As I mentioned we use this as an intranet at my company and not having the directory available for weeks now has not been good. Please let me know how I can work with you to resolve this.
