Do you still have access to your exchange account? If so then you can export all your mailboxes, contacts, calendars etc directly to a .pst file.
Go to file, options, advanced, export
Choose “Export to a file”
Choose “Outlook Data file (.pst)”
Select the items you want to export and check the box to include subfolders
Browse to where you want to store the .pst and click finish.
If you don’t have access to your exchange account then you can convert an EDB file to a .pst file but you will have to buy software to do this.
I can’t recommend any software to convert the EDB file since it’s not something I have ever needed to do.
Hopefully you still have access to your account
