The only converter which converts a NSF file into PST c
jeremyhodgsonNovember 20, 2017
Pros
Transferred all the contacts journals and mailbox with good precision.
Cons
None...............
Summary
I tried many lotus notes to PST converters but none of them were performing up-to my expectations as some converters interchanged the cc and bcc and some converters missed a few contacts here and there, however Stellar NSF to PST Converter exceeded my expectations as each and every mailbox contact, calendar and journal was converted with 100% accuracy.

Not any.....
Summary
With the help of this Stellar NSF to PST converter, I was able to migrate to Office 365 in a very economical manner (Many software were charging on per mailbox basis). The software converted all my emails, attachments, journals and contacts into Office 365 without a problem and too very quickly.
EXCELLENT PRODUCT!!

Cons
This software has no cons I would say. It was a great experience with this software as it successfully exported every NSF file object to PST.

Easy to use, great for conversion
Damon_July 13, 2015
Pros
Tried Tech version of this tool & I must say, this tool was simply outstanding. It successfully converted my 12 GB NSF file objects to EML format in quick time.
Cons
Cons! Are you kidding? I think Cnet should remove the section of Cons from this tool. I couldn't find any cons of this tool.
Summary
This tool is did exactly what Stellar has advertised. I have tried Kernel's tool for conversion before but the results it gave was not at all satisfactory and I asked for the refund. After that, tried Stellar NSF converter and this tool fulfilled my need completely.
Quite better than others

Pros
Fast, reliable and never fails to perform conversion
Cons
None so far
Summary
Converted the mail components of my NSF file to PST file in a timely manner and when I imported the PST file into Outlook to check the data, I found the same data intact with the same structure as it was in lotus notes. Overall, I'm really with the way software performed conversion?
