Currently, St. John’s University offers 100GB of storage in the Office 365 mailbox. Emails in your Office 365 account are accessible on any device. Emails saved in your personal archives (.pst files) are stored locally on your computer.


It is not possible for IT to automatically move them to your Office 365 account. However, you can use the instructions below to manually import .pst archives to your M365 account — giving you access to all of your emails from any device.


Windows

  1. Open Outlook

  2. Close all .pst files you want to import (right-click the .pst in the folder list and choose Close Outlook Data File)

  3. Exit Outlook

  4. Relaunch Outlook 

  5. Choose File > Open & Export

  6. Choose Import/Export

  9. Browse to the .pst file and click Open

  10. Choose whether you want to allow, replace, or not allow duplicate items. Then click Next

  11. If you want to import the entire .pst file, select the main folder containing all subfolders. Then select the checkbox labeled “Include subfolders”.

    • If you only want to choose certain folders, expand the Outlook Data File until you see a specific folder you want to import. Select that folder. Then select the checkbox labeled “Include subfolders.”

  12. Select the option labeled “Import items into the current folder” and click Finish 


The emails and folders should appear in the currently selected folder. You can drag and drop messages and folders to other locations.
