I need to convert some 50,000+ files, that have been saved by a client to a flash-drive apparently as Outlook 2013 files, to one PDF file. I have looked at some software, but these seem incapable of coping with volume of files and converting both the outlook file and the attachment. The object is to avoid printing off the emails and attachments which would amount to circa 1 million pages.
My other difficulty is that the Outlook files do not seem to be what I gather should be PST files.
I am not very technically minded.
