We are using SharePoint 2013, users is having office 2016, Now in Document Library --> Open with Explorer -> Right clicked and created Excel Document --> Double clicked to add data in excel. Now here in my Development environment I'm able to add data in excel sheet and its get saved in my document library using Open with Explorer as per above steps.
But same thing when I'm trying to do in my production, Document Library --> Open with Explorer -> Right clicked and created Excel Document --> Double clicked to add data in excel then after opening the excel its shows message "CHECK OUT REQUIRED
To modify this server workbook, you must check it out." because of this I'm not able to add the data in excel. This message I'm not getting in Development Environment.
