Before conversion, review the OST folders and select the required emails, contacts, calendars, tasks, notes, or other items. Make a backup and copy of the original OST file so the source data remains untouched. I suggest using WholeClear OST to PST Converter. It is also advisable to check if the OST file is accessible or damaged and make sure that you have enough free space to save the PST file.
It will also be helpful to see if there are any issues with your OST file, such as corruption or lack of sufficient storage space for the PST file.
Prior to converting the OST file, it would be wise to explore the contents of its folders and choose the email messages, contacts, calendars, tasks, notes, etc. that need to be exported. WholeClear software allows users to preview the content of their OST file prior to converting it to PST.
It is also important not to depend on an existing Outlook and Exchange connection.
If you are unsure about the state of your OST file, I would recommend using a free version to check your recoverable OST data.
