Users Queries

Query 1. I began business as a sole proprietor and started using Lotus Notes NSF for managing and organizing the emails of our subscribers. However, I am not fully satisfied with this email Client because it has a complicated interface. Sometimes I feel Lotus Notes is much harder to organize and manage. Therefore, I want a perfect understanding of the user interface of an email client. That is why I am considering migrating the entire Mailbox of Lotus Notes NSF to Microsoft Outlook.
