want to open another .ost to view it's contents - easy 500!

I have an Outlook0.ost file that I believe contains some missing mail. The profile is currently using Outlook.ost. I would like to open the Outlook0.ost but don't want anything to change (add/delete) unless I manually do so. Is this possible? They are both from the same local Outlook profile, residing in the same default directory local to the pc.
I have a user who had pc's swapped and he complained of missing mail. I see on that same day is when the Outlook0.ost file was last modified (over a month ago). I'm wondering if something got corrupt, so want to see if the missing mail is in there.

I would recommend making a copy of the OST file, then convert the ost to pst using this:

then you should be able to open the PST file in outlook and check it for your missing files.

Hope this helps!

Use that to convert the file.

I would not recommend trying to open it as an OST file, as it is set to automatically sync with the exchange server, and could potentially lose the files you're trying to recover.

The second link I provided is a free tool to convert it to a PST, which you can open seperately in Outlook. I recommend making a copy of the OST to work with in case something goes wrong with the conversion, or opening of the file. (Just in case measures.)
