How to open a local client archive .ost file on a new computer We use Exchange 2010 Standard and Outlook 2013. I got a new computer and made a copy of my email archive that was being stored on my Windows 8 computer under c:usersUserNameAppDataLocalMicrosoftOutlook. Now I want to open the archive to look for an old message. Outlook 2013 won't open the file. Error, "The file you chose is not an Outlook Data File. You must select a new file of this type." Outlook 2013; File Menu; Open & Export; Open Outlook Data File - that will open the file browse window with the file type of Outlook Data Files listed. To show the archive, I had to change it to All Files.  The file extension is hidden, but the details of it show the Type is "Outlook Data File". If I try to open it, I get the error above.  Looking at the properties of the file, it is an .OST Outlook Data File. I know that Outlook wants to open a .PST file, but I need to open an .OST file. The Exchange Server did not change. The network user did not change. The only thing that changed was the old computer was removed from Active Directory and the New Computer was added - and the network user properties was updated to the new computer.

Thanks. We'll let you know when a new response is added.

It looks like your OST file had become inaccessible; you may need to convert your OST file to PST. After synchronizing once with your exchange, you can recreate your OST again from it:

For this you can try OST to PST conversion software like KDETOOLS OST to PST Converter, Stellar, systools, Kernel and many more, which allows converting OST file into PST providing access to inaccessible data.

    OST-files aren't intended to be reused. You need to reconnect to Exchange and Outlook will recreate the cache again.
