I have a couple of backed up .pst and .ost files that were used with a server that is not accessible anymore. On my local machine, I was able to Add... the .pst file to my fresh Outlook 2007 and access the emails. However, adding an .ost file does not seem to be an options in the Accounts Settings dialog.

Is it possible to import the .ost file, or convert it to a .pst w/o the aid of the exchange server?

you can find many software that will do that for you: – JMax Sep 26 '11 at 7:43
Thanks @JMax - I was hoping for a method from within Outlook or Office. Google search found only paid software. – ysap Sep 26 '11 at 8:51
unfortunately, as .ost and .pst are proprietary formats from MS, I don't know if anything out-of-the-box would work. Maybe these software have a trial version? – JMax Sep 26 '11 at 8:56
The couple of software I found have a limited trial version that won't let you go all the way to actually create that .pst. – ysap Sep 26 '11 at 9:16

In the past I faced a similar problem and fixed it with programs like

  1. ostpst
  2. osttopst
  3. ost2pst
  4. Systools

Thanks, @davejal. It has been a while since asking the question, and I don't have access to these files anymore, so I cannot verify your answer. Hopefully someone out there will find it useful. +1 anyway. – ysap Nov 7 '15 at 0:11
