Many users want to fix this issue but they did not get the best tool to fix this issue, so here I recommend you SysInspire NSF to PST converter software. This tool converts NSF files into multiple file formats such as NSF to PST, EML, EMLX, Office 365, Yahoo Mail, Gmail, etc. It has 15+ file formats for conversion of NSF files. It has a demo version that allows users to convert 25 items from each folder. This tool imports emails with attachments.
