Importing PST files into Office 365 can be a little tricky, especially if you have a lot of files or mailboxes. I had the same problem when I had to convert my Outlook data to Office 365. Not only did manual procedures take a long time, but they also put data at danger of being lost or mapped to the wrong folder. After a while of trying to fix things on my own, I decided to hire a professional, and it made a tremendous difference. I utilised the
WholeClear PST to Office 365 Converter, and that made the whole thing easier. The software imports PST to Office 365 straight without any complicated setup, and everything was moved over precisely as it was.
Things I Did
Install the software and start it up.
Put PST file(s) into the tool
Look at the mailbox data before you start
Type in your Office 365 login information.
Choose folders or the whole mailbox to import.
To start the procedure, click the migrate button.
