To avoid losing data and make sure the transfer goes smoothly, you need to prepare ahead of time when moving PST files to an Office 365 mailbox. First, it is necessary to make sure that the PST file is intact and that the user mailboxes are mapped correctly. There are ways to do things by hand, but they can be hard and take a long time, especially with a lot of data. I had this problem before when I was working with more than one PST file and it was not particularly efficient. After that, I utilised FixVare PST to Office 365 Migrator, which made everything easier. It made direct PST to Office 365 migration easy and kept the email attributes, attachments and folder structure correct. The interface was easy to use, so you did not need to know a lot about technology to use it. The free demo version was also useful for testing the tool on a small amount of data before moving everything over. In general, selecting a trusted service made the whole process of moving quick and easy.
