My first suggestion will be to go for a manual method in
order to convert EDB files to PST format. The first method will be using GSTECH
EDB to PST Converter
tool. The files should EDB files can be exported to PST format with import
Another method is to use Power Shell command to export the EDB files. However, if the above steps do not work out then you can try any reliable EDB to PST converter.
