Lotus Notes is a remarkable email client application, introduced by IBM. It is known for delivering secure business communication task like instant messaging, microblogging, appointment scheduler etc. The application is equipped with IBM Domino Server that handles the Lotus Notes storage and administration part of user email profiles and act as server-side software. Number of large organizations make use of IBM Client-Server architecture to carry out the process of email communication in more secure and authentic way. However, Lotus Notes email client is more than just an email application because it is designed to deliver business services such as workflow management, document management, request approval and more. Also, IBM Notes can integrate intelligent databases and apps of IBM Domino Server. Due to such reasons, organizations started to think of switching to a more complex-free email platform. 

Why to Move from Lotus Notes to Microsoft Outlook?

There are many essential features added in Lotus Notes and Domino Server apps that makes the email client more expensive and sophisticated. Hence, several organisations are trying to move from Lotus Notes technology into simple and more user-friendly email client like MS Outlook because some companies need efficient as well as effective email app rather than a sophisticated or complicated configuration unit. Some of the main factors that influence the organisations/employees to move from Lotus Notes to Outlook email platform:

The Lotus Notes and Domino application database is based on NoSQL technology that offers a granular security level that can be applied by taking 10 different conditions. In order to handle highly secure data folders, the provision of technical experts should be made. However, if we talk of MS Outlook, it works with synchronization of MS Exchange Server that supports a simple Active Directory database.      

IBM Domino stores all information in NSF that stands for Note Storage Facility, and each note is denoted with a UniqueID. In spite of this, many different notes exist that do not follow the methodology of relational databases. Thus, it is a complicated process to manage/retrieve NSF email files. Whereas, in MS Outlook, all its email files are stored in PST and OST, that is easy to access by any authorised user.

In IBM Lotus Notes or Domino Server, entire email items, applications, and configurations are stored in the Notes Storage Facility (.nsf) instead of any Windows registry. This type of IBM Notes backup mechanism, at times, becomes a disadvantage during disastrous circumstances. On the other hand, Microsoft Outlook backs up all its data files in OST, PST, and other various Windows registries. Thus, it is clear that Outlook easily comes out safe in many challenging conditions. It secures the essential data of the Outlook user account without affecting the integrity.

Apart from this, MS Outlook emerging competitive email application due to the following reasons:

Less Cost

Outlook is an inexpensive email application compared to Lotus Notes because to maintain and monitor IBM Notes, one needs to obtain and pay wages/salaries to qualified technical professionals. 

Friendly Interface 

MS Outlook was developed with ultimate ease and an amusing graphical user interface that is helpful for different user categories. With Microsoft Outlook, a user can retrieve any email and other collaborative services without having for Administrator role.

Outlook also acts as a personal information management tool as it can help in scheduling appointments, sending emails, organizing, and even managing contact data, etc. by engaging with the features present on the default screen. Thus, users using IBM Notes can execute their tasks quickly. 

After understanding the main benefits of Outlook, companies are frequently moving onto the same, but in carrying out the migration, companies are desperately looking for a reliable utility.
