Open Outlook OST file

for various needs it can happen to find yourself with an outlook ost file and not know how to handle it. first of all a clarification, unlike pst files, for which through outlook has provided for the import or direct opening, for ost files this is not possible, I tried a series of ways but none of these allowed me to do so, except for the use of third-party and paid software. ost files contain all the structure of the mailbox, so inbox, sent, etc., and are generally created by outlook when the user uses exchange server with Cached Exchange Mode. once the connectivity with exchange is interrupted or the ost files are stored or backed up and moved to another machine, the ost files are orphaned and ms outlook no longer recognizes them, thus preventing them from opening. in addition to exchange, outlook creates ost files when the user configures the hotmail account in outlook and configures a gmail account with imap. in both situations, ms outlook creates ost file but once updated or deleted your profile becomes inaccessible and it is precisely in these cases that you wonder how to open the ost file without exchange server or ms outlook. obviously I did not spend sleepless nights trying to find who knows what archaic solution, even if the thought I had, but after a series of attempts the ways to follow to open an ost file were mainly two: use a viewer to read the history of emails or use one of the various paid software to convert the ost file to pst, as I said before, the pst file is easy to consult via outook. in my case it was an old box, so I limited myself to using the viewer, among other things there is a free and rather working one that was enough for me to get what I needed, the official website is this mailsdaddy, from which you can easily download the file. if instead the need is to pass on outlook directly the ost file I bring you back to follow some converters, but all paid: stellar, recoverytoolbox or the same mailsdaddy. recoverytoolbox ost pst converter is the cheapest (to date).
