WHAT: This option lets the user automatically import a .pst file using the Import/Export option. In most cases this will speed the process up and make it a bit easier for the user.

1. Install Outlook 2016 from Office 365.

Open Outlook 2016. You can still use 2013 if that is what the user has but only 2013 and 2016 will work.
Disconnect all PSTs to be imported from the Outlook client (e.g., right-click on your .pst in your folder list and choose Close “.pst”.

i) Do this by going to File > Account Settings > Account Settings > Data Files tab > Remove then Close.

Exit Outlook and then relaunch the Outlook client to assure the PSTs are free from any connections from the client.
Create destination folder in the Office 365 mailbox that correspond to each PST to be imported. You can also use the Archive folder that is already in Office 365 and shows up in your Outlook.

Select by clicking on the the destination folder you wish to import the .pst file into. (NOTE: this is the folder the mail will be imported into).
Choose File | Open & Export.
Choose Import/Export.
Select “Import from another program or file” and click Next.

Select “Outlook Data File (.pst)” and click Next.
Browse to your .pst file, select it, and click Open.
Choose whether you want to allow, replace, or not allow duplicate items. Then click Next.
If you want to import the entire .pst file, select the main folder containing all subfolders. Then select the checkbox labeled “Include subfolders”
OR
You can Expand the Outlook Data File until you see a specific folder with the emails you want to import, Select that folder. Then select the checkbox labeled “Include subfolders”
If you want, you can use the “Filter…” button to use advanced features such as importing emails with specific text or from specific people.
Finally, select the option labeled “Import items into the current folder” and click Finish.
