I have recently gone through an informative article that provides the two best approaches to migrate Lotus Notes to Office 365. You can refer to this article in case you want to import the NSF files into your Office 365 admin account. This article will also provide you with the main benefits to migrate Lotus Notes to Office 365. The following 4 steps are discussed here to perform this migration manually. 

• Create a Backup of Lotus Notes NSF Files.
• Create a New Mailbox Folder for Each NSF File.
• Enable the IMAP TCP/IP Port.
• Configure With IMAP Connector.

However, this manual approach requires technical knowledge and has some limitations that make it quite tedious for non-technical users. In this regard, experts have always recommended opting for a reliable utility that ensures high data integrity. In this context, this article will introduce you to the Cigati NSF to PST Converter. This software has a self-explanatory user interface that is compatible with both technical and non-technical users. You can also try its free trial version to analyze the performance of this advanced utility.
