If you are in search to export lotus Notes emails with attachment, I would ask you to download the SysInspire NSF to PST converter.
I suggest the SysInspire tool to export Lotus Notes emails because this is a three-step process which means scan, preview and then export the Lotus mails. All the email properties will be easily expired. Email contents mean the To, CC, BCC, DATE, etc. Also, Lotus Notes version 9.1, 9.0, 8.5 and the other lower versions are favoured.
By using this nsf converter tool, you can convert all the emails present within an NSF file along with attachments of any type including; images, documents, etc. The software can export the attachments and access nsf files with Outlook. You can also save any particular attachment by right-clicking on the attachment icon.
Go and install the SysInspire NSF to PST converter tool and export Lotus Notes emails with all the attachments. You will have to scan, preview and then put on the final option to export the email contents.
