I have Outlook 2007 that is currently working with MS Exchange at a HOSTED datacenter.  I will lose my Exchange access in a few days but I want to ensure that I still have access to the emails that are currently on my PC.  The files are located locally in an OST file (see attachment).
When I lose my Exchange access I assume I will still be able to access the emails that are located in the OST file.  Should I leave them there or move them to a PST file?
After I lose access to Exchange I will connect my Outlook to a POP EMAIL account and would like to have the TWO instances separate but accessible.
Appreciate all suggestions,
Thanks!

Introduction to Outlook Data Files (.pst and .ost)
Do not assume anything!
For your own PEACE of mind, backup the e-MAIL folders before the service stops. The general method is:
    Select File > Open & Export > Import/Export.
    Select Export to a file, and then select Next.
    Select Outlook Data File (.pst), and select Next.
    Select the mail folder you want to back up and select Next.
    Choose a location and name for your backup file, and then select Finish.
 Better safe than sorry.
