Migrating from Outlook 2003 to Outlook 2010: how to avoid the creation of a new .ost file when creating a new outlook 2010 profile

Hi all,

We are currently migrating our environment from Office 2003 to Office 2010, and especially Outlook 2003 to outlook 2010. Because most of our users have very large .ost file, and are also located in branch offices, we would like them to keep the existing .ost file when doing our migration, but we also need at the same time to create a new outlook 2010 profile as generally recommended. We would like this in order to avoid the creation of new .ost file which could be time consuming and network bandwidth consuming.

Any options? tools? workarounds?

Note that we built our Office 2010 package with OCT, and that our Exchange infrastructure is Exchange 2007, and cached mode is enabled.

Thanks in advance - Regards

LB
