Outlook backup

I'd like to create a backup of my entire Exchange inbox and store it at another location. I don't have access to the Exchange server and hence I need to do this from Outlook.

Now my Outlook is configured for 'cached exchange mode' and I see a outlook.ost in my profile folders.

1) Is this enough or should I resort to another form of backup?

2) Is an .ost file just like a .pst? Can I simply rename it as .pst and it'll still open up fine?

    no, .ost is not just like ost.  go to file > import/export > export to another program or file > choose personal folder file > choose what you want to backup and export away.

    never rely on an .ost as a backup...EVER! :)

    You can use a program called the Personal Folders Backup Utility.  You can go to and download it.  It works pretty well.
