Answer 1

Converting an OST file to PST depends on whether the original Outlook profile is still accessible. If the account is active, you may be able to export the mailbox through Outlook’s Import/Export wizard. However, when the OST belongs to an old profile or Outlook can no longer access the mailbox, direct export may not be possible.

In that case, TrustVare OST to PST converter is an alternative worth trying. It lets you load the OST file, preview its mailbox contents, select the required folders, and save the data in PST format. During conversion, you can extract emails, attachments, contacts, calendars, and other supported items.

Before using the resulting PST in Outlook, check that the important folders and attachments are present.
