Using an existing OST file on another computer

Quite often we find that an existing Exchange Online user needs to set up their Outlook profile again for various reasons (new computer, changing office locations, etc.). Thanks to the sign on tool this is a no brainer.
The issue however is that we don’t want the user to download their entire mailbox all over again.
The solution? Move their existing OST file to the new computer and configure it for use under the ‘Data Files’ or Cached Mode settings.
For the steps involved – have a look at this Microsoft Office Online help article. While the article is specific to Outlook 2003, it also works for Outlook 2007 and 2010.
