Hi, I'm James Robert, working as a Database Engineer at Cigati Solutions. Our company specializes in Email Migration, Data Migration, and File Conversion. We recently developed the Cigati PST Converter Tool to simplify the processes of importing PST Calendar to an Office 365 Account. With this tool, you can also convert PST files to various other file formats, such as MBOX, EML, EMLX, MSG, PDF, CSV, GIF, etc.
