Hi Tom,

You can follow the below methods to convert OST files to PST:

Method#1: Archiving
Outlook email client offers the facility to Archive data by moving the OST mailbox folders to PST file format. The process can be accomplished in the following steps:
  1. Launch MS Outlook application.
  2. Click on ‘File’ menu and select ‘Archive’
  3. Select the folder(s) or file(s) that needs to be archived
  4. Select destination location for Archive storage on computer
  5. Click on ‘Finish’
Method#2: Export/ Import Wizard
Exporting of OST data to PST files is probably the most scalable method and serves as one of the preferred OST to PST converter options. To accomplish the export procedure follow the undermentioned process.
  1. Open Microsoft Outlook 2016, 2013, 2010 or previous version
  2. Navigate to ‘File’ menu and select ‘Import & Export’
  3. This will open ‘Import and Export Wizard’, select ‘Export to a File’
  4. Further, select ‘Outlook data file’(PST) format from the given storage options
  5. Make sure to select the checkbox associated to ‘Include subfolders’
  6. Click on Finish
As far as the Import and Export procedure is accomplished, Outlook will start converting all the components of OST file to PST unless an existing password protected PST is selected.
  • If the export is done to an existing password protected file then enter appropriate password to the dialog box that says ‘Outlook data file password’ and click on the ‘OK’ button.
  • On the other hand, if you wish to provide a password to PST file, type password in the ‘Create Outlook data file’ box and then click on ‘OK’. ‘Outlook data file password’ box will appear, type the password and click ‘OK’.
Now, once mailbox data is available in PST file format, it can be transferred or moved to new location in your computer or external storage drive.

Method#3: Convert Outlook OST file as PST using OST PST Tool
It is possible that your all attempt failed by following the above methods. In that scenario you should choose the automated solution to convert an Outlook file data as PST, as it the guaranteed solution to complete the OST files conversion job in the first attempt. Try the software and convert the Outlook OST file into PST form.

I hope this helps.

Since OST file is the storage of the data by Outlook there is no fixed way to open it. But in case you still want to open it. you will have to find a OST file viewer which is a 3rd party viewer. There are many in the market but make sure to find a good one.

I case you can't still open your file it may be corrupted, in that case, you can use an OST to PST software to recover your files as well as convert it into a more secure PST file.
