Troubleshoot All Outlook 2007 Archives won’t open

[mitrywing]

None of the archive email folders (PST) open to an account. ALL will not open. The lastest reached about 20 GB on Friday, then all became inaccessible even though they are individual pst files. I just see a tree list of folders and can not open the emails. Scanpst might chop away valuable mail. Any clue's why this has happened? Or how I can retrieve the archives?

To fix corrupted PST files, you can use the Inbox Repair Tool. However, the tool isn’t always able to repair every PST file. It works by repairing the PST file’s header and then deleting anything in the file that it doesn’t understand. So if a PST file’s header is damaged, as may be the case for corruption that occurs during a version upgrade, the tool should have no trouble making the repair. But if the data within the file is corrupt, the Inbox Repair Tool will likely destroy what’s left of the file. That’s why it’s always good to make a backup of the PST file before running the Inbox Repair Tool.

The Inbox Repair Tool is located in the C:\Program Files\Common Files\System\Mapi\1033\NT directory of any system that’s running Windows 2000 or Windows XP. The tool’s filename is Scanpst.exe. Other versions of Windows also include the Inbox Repair Tool, but the tool’s location varies among these earlier versions.

create a batch file that deletes the ost file upon logon. outlook will then recreate the ost file.
del %userprofile%\appdata\local\microsoft\outlook\*.ost
try this
C:\Program Files\Microsoft Office\Office12\scanost.exe
Quicker to rebuild the OST and download all the emails from the server. OST scans take forever and useless since all the emails can be retrieved from the server. PST files..different
