e-mails that are only saved in outlook!

"cannot open your default e-mail folders. the
file.C:\Users\Jackie\appdata\local\microsoft\outlook\outlook.pst cannot be
accessed. data error (cyclic redundancy check)."

The CRC error usually means the pst is corrupt. Try using scanpst.

No such product. There is Outlook Express (v6 is latest) or Outlook 2007
(an MS Office component).

All of sudden you opened Outlook? No impulse control? );->

Looks like we guess that you are using Windows Vista (or maybe Windows 7)
since prior versions of Windows had a different default path for user
profile folders.

You .pst file is corrupt. You could try to use the Inbox Repair Tool
(scanpst.exe). See:

http://support.microsoft.com/kb/272227
http://support.microsoft.com/kb/287497

If that doesn't work, restore the .pst file from your backups. If you don't
backup, you deem your data as worthless or reproducible.

Since others haven't mentioned it, CRC errors are indications that your hard
drive may be failing. The first line of attack on this, after trying to fix
the PST as others described, would be to use chkdsk to scan your drive for
errors. Consider also, getting a tool like SpinRite
(http://www.grc.com/sr/spinrite.htm). $90 may seem a lot, but if your data
has any value, it can be well worth it and Steve Gibson offers a money-back
guarantee if you're not happy. SpinRite has restored to operational status
many disks that otherwise would have been thrown in the trash. I have no
vested interest in SpinRite. I've heard plenty of reports about it, though.

Slamming shut a network connection to a .pst stored on a mapped drive is
another cause for corruption of the .pst file and why Microsoft does not
support use of a .pst file across a network. Windows crashing so that the
file isn't gracefully closed is another cause, especially if not using NTFS
and instead using FAT.

I had Spinrite several years ago. Excellent product for reviving a hard
disk. However, other than re-alignment, the repaired disk should be
considered flawed and temporary until you get a replacement. The cost of
getting Spinrite is usually outweighed by getting a new hard disk at a
cheaper cost; however, as you mention, you may not be able to retrieve your
data from the flawed disk. In the scenario where you work on many hosts
(computer shop, IT dept, test lab, etc), Spinrite should be part of your
recovery toolset. If I could find my old copy then I'd upgrade at lower
cost, but the initial cost to buy it new doesn't make sense versus just
buying a new hard disk for the same money (since you're probably going to
buy a new hard disk, anyway, even after using Spinrite to repair the failing
one).

Realignment or refresh would be the only 2 fixes from using Spinrite where I
would continue using the old hard disk. As I recall, there is a deeper
sector inspection available in Spinrite to catch the bad ones before the OS
detects a bad sector (because the OS permits up to 15 tries to read a sector
which slows access and means the sector is going bad).

hey, thanks for the advice! i tried to run the "scanpst.exe", but when i did,
this error came up!:

"an unexpected error prevented access to this file. use a disk error
checking program to check the disk, and then try using the Microsoft Office
Outlook 2007 Inbox Repair Tool again."

ahhhh! whats wrong and how can i fixx it?

Like I said, it appears your hard drive is flawed. We've discussed what you
should do already.

If you find yourself in a situation where you cannot solve the issue (because there is a true corruption on the hard disk) or when you managed to recover the pst-file but no longer can open it or recover it via scanpst.exe, you can then try repairing or salvage recoverable items via a 3rd party recovery tool
