If you want to shift your email client from Outlook to Office 365, then you are at the right place and you need to migrate PST to Office 365 first. But, it is not easy to complete this migration task from PST to Office 365 because even a single mistake can cause data loss. However, choosing a manual method to do this task is not a good idea for non-technical users, so it’s better for users to opt for professional software. Moreover, there is a lot of professional software for this task, but I suggest users try the Shoviv PST to Office 365 Migration tool.
