I have a .OST file that needs converted to .PST. Exchange server that this file came from has been dbanned.
This post about OST & PST viewers seems promising, to view the files... but it states those tools don't have export abilities.
Looking for a needle in a haystack of "trialware", the closest thing I've found is this Spiceworks topic with this answer which seems promising:
Artie Jan 12, 2012 at 3:26 AM You can use outlook to do this recovery but it is a bit of a round-about way. Outlook itself will not let you attach an OST file... What you can do however, is configure Outlook under a separate profile with the user in question's connection (to build the proper authentication certificates). Build it making sure to check the box for Offline use.
Once it is connected, force outlook into offline mode (I usually pull the network connection as well just in case). With outlook forced to offline mode, close outlook. You can now delete the OST file that was just created and replace it with the OST file that you wish to recover from. (NOTE: there is a process from task manager you will have to close that monitors the OST file to not let you delete it, I don't remember off the top of my head what it is, but i remember the name being fairly obvious.)
Start Outlook back up (it should still be in forced offline mode. It will take a few minutes as it builds all the data from the Recovered OST file. Once it is up and running, move EVERYTHING over to a PST file, and you will be good to go.
The thread also has this brothersoft tool linked that seems promising. As long as the "Full Trial" is true, I'll be able to use it the one time I need it (Safely in a virtual environment to ensure I don't catch anything).
I'm not really looking for a product recommendation, as much as I'm looking for a solution to a one time issue. There seems to be plenty of (overly advertised) options, so someone who wants to spend $100+ can find a solution. That's a steep price for a one time issue.
I'll try the offline option and the "30 day Trial" option and post an answer if either works, or I'll try other answers if others have better options.
