If you're like me, you're constantly going to look at the offline folders file, outlook.ost, to see exactly how large your offline mail is. Or you may be looking to delete extend.dat, or any of the other cache files. Now, along comes Vista, and things are a little different. Well have no fear, it's not too hard to find.

I'm used to looking in C:\Documents and Settings\%username%\Local Settings\Application Data\Microsoft\Outlook, and of course, that's not a user accessible path anymore.

In Vista, just go to C:\Users\%username%\AppData\Local\Microsoft\Outlook, and you'll see all of the files that you've come to know and love, including the offline folder files.
