Frankly I'd just import it into Thunderbird. Here's how.
About 3 years ago, while changing computers, I manually backed up my outlook files (only had emails in them). I really wanted to save some stuff, so followed the directions I found on the web or on Outlook 2007. They are in a folder called outlook backup.
I can't remember why we did not restore the files, but we didn't. It seems like Outlook wouldn't bring them all back in or something like that and we only restored part of them. But I might be wrong.
Anyway, when you try to open it, it says it's a system file (.pst). It says don't open the file, as it could cause system problems, then it implies you can open it with several different programs (Adobe reader, Word, Paint, Explorer, etc.).
In properties it says it's 1 file of 348 mb and is read only.
Once I get it open, I'd like to do a keyword search to retrieve some family history files sent to me, so I don't want to screw up the files. I also don't want to open them as picture files unless that's the only option.
My idea was to make a copy of the file and try to open it with one of the programs they say will open it.
Will that work? Any better ideas?
