Coming to the selective export of 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.
By using this time-saving utility, provides the “date range filter” peculiarity that permits to convert the selected file components by choosing the two specific dates. The Lotus Notes version 9.1, 9.0, 8.5 and the other lower versions are favoured.
Go and install the SysInspire NSF to PST converter tool and export Lotus Notes emails with all the attachments. Yes, there is no limitation about nsf size; you can convert unlimited data from NSF file to pst and other given formats.
