asked on OST files when upgrading from Office 2007 to Office 2010
I'm currently testing an upgrade from Office 2007 to Office 2010. When I open Outlook, I receive a prompt; "Outlook is using an old copy of your Outlook data file (.ost). Exit Outlook, delete file and restart Outlook..."
Is it possible to upgrade the existing OST or do anything to avoid doing this?...
I have 64 sites using a remote exchange server in a datacentre with a 10mbps line. All my sites use ost files and would need to download their mailboxes again... I'd like to avoid this.
Thanks
John

The OST file is a replicated copy of a mail file from your Exchange server. My suggestion is that you delete the OST copy and resync it after O2k10 is installed.

The problem was only present in my initial testing machine and didn't actually occur in further testing. However I think that this post is correct and it was due to the type of OST (ANSI) on the test machine.
