I have a large number of emails saved in TGZ file format (exported from Zimbra), and now I need to access them in Microsoft Outlook, which supports PST files. Unfortunately, Outlook does not recognize TGZ directly. Can anyone suggest an easy and reliable method to convert TGZ to PST? Is there any manual solution available, or do I need to use a third-party tool? I am looking for a step-by-step solution that won’t risk data loss (emails, contacts, attachments, etc.).
