Recovered Outlook public folder has no contents

Hi,
A public folder in Outlook was accidentally deleted and we are unsure when this did happen. What I did to recover said folder was use the "Recover Deleted Data" inside Outlook. However, the recovered folder is missing 99% of its supposed contents. What would be my next steps in recovering the data in the public folder? I am a beginner in Exchange.
Thanks.

 

Actually the data are stored in a local OST file and what you need to retrieve the data is just convert and recover the data from the local OST file or from the Exchange account on the server.
There are several methods to convert OST file to PST file.
First, Microsoft does not provide an official tool to do the conversion. However, if you can access the contents of the OST file in your Outlook, then you can perform the conversion manually, as follows:
1. Start Outlook. Make sure you can access all the contents in the OST file to be converted.
2. Create a new PST file.
3. Go to the OST file, select and copy all the contents to be converted with your mouse.
4. Go back to the new PST file, then paste all the contents into the PST file
That will do the conversion.
You can also perform the conversion by export the contents of the OST file to a PST file by following the instructions at:

Second, if you can access the Exchange server containing the account data for the OST file, then you can use Export-Mailbox command to export the data into a PST file, similar to convert your OST file into a PST file. Below is the article about doing that:
