Wonder to see that a third party solution can migrate data from Lotus Notes to latest Outlook version with higher success rate.

Great piece!

Terrance Clayton


Last month, Our Company had decided to switch on Outlook 2016. Then, we had consulted with many experts for a safe migration. But, their proposals were not budget friendly.
Fortunately, our IT manager discovered this tool on SpiceWorks community. We can say that this tool saved us from financial burden.

Why Office 365 is limited to technician users only.



We never imagined that a tool could perform the conversion easily. Your technical team is also supportive.

Danny McGray


Now, I can believe that a software can migrate multiple mailboxes without the assistance of any Server expert.



Why is demo version limited to 10 items per folder? This useful tool should be free for a start-up business.

100% correct log report. Now, I can recommend this software to our partner companies.



Definitely, the software works well but $499 seems expensive for an entry-level tech support company.
