Outlook 2003: Restored Exchange Information Store but OST Folders are Taking Precedence

[Neil Hoskins]

I fell in to the trap of not realising that Trend Micro's "scan all files"
actually means "scan the entire Information Store and permanently delete all
attachments".

I managed to restore the Information Store from backup tape after over a
week of fannying about, but now everybody's OST files seem to be taking
precedence over the Exchange files, and everybody's email attachments are
still not visible. If you uncheck "use cached Exchange mode" and restart,
they appear again from the Exchange server. In the longer term I want to
use offline storage. How do I synchronise OST and Exchange, with Exchange
having precedence? I successfully did a workaround by replacing one
outlook.ost file with a completely blank file of the same name, but is there
a more "elegant" way of doing it?

Hi,

this always worked for me:

1) turn off Exchange Cached Mode
2) close Outlook (also check Task Manager for outlook.exe)
3) delete OST file
4) turn on Exchange Cached Mode

Not sure if this is elegant, but it works.
If you have a large number of PC, you can set to disable Chached mode via
Group Policy, delete OST file via script at user logon, enable cached mode
after few days.

Hope this helps,
Jevgenij

Thanks. That should make it a bit easier.
