However, there is a difference between these two email clients, where NSF (Notes Storage Facility) is a file format used by Lotus Notes, Microsoft Outlook uses PST (Personal Storage Table), and OST (Offline Storage Table) file format to store data.

Many users are switching from Lotus Notes to Outlook, seeing the changes in their business requirements and market. There are many reasons behind the conversion of NSF files to PST format. Stuck with the blog till the end and convert your NSF files to Outlook PST file format effortlessly.

Reasons that initiate users to convert NSF to PST file:

The reason to prompt users to export from NSF to PST file format varies from user to user. However, some common causes that trigger users to move from Lotus Notes to Outlook are listed below.

  • Being a product of Microsoft, users found Outlook more convenient in terms of presence and availability. Outlook is also a part of Microsoft 365.
  • No one can neglect the price comparison as cost-efficiency is a measure that remains the basis of all comparisons. When compared, using MS Outlook is more cost-effective than Lotus Notes.

  • Outlook offers offline availability of the mailboxes, while this is not possible with the Lotus Notes.
  • MS Outlook provides its users with a wide range of advanced technical features and security services compared to Lotus Notes.

The manual method is neither an absolute nor a preferred method for professionals. There are some drawbacks and limitations that professionals should be aware of. A few of them are:

  • The manual process does not guarantee a complete conversion of the NSF file to PST format because it does not convert the calendar entries.
  • The manual process has a high chance of failure due to various human errors.
  • This process is very time-consuming, as it can only export one NSF file in one run. It has expensive setting-up costs as well.
  • Selective conversion and specific conversion of items is not possible.
  • With the migration of manual processes, there is a high threat of data loss.
