I have been using Mozilla Thunderbird for years to manage my emails, but now my organization is migrating to Microsoft Outlook. I need to convert a large number of Thunderbird emails into PST format so they can be accessed in Outlook. The problem is that I have multiple folders, attachments, and important emails, and I do not want to lose any data during the conversion. Manual methods seem complicated and time-consuming, especially for non-technical users. Can anyone suggest the best and safest solution to convert Thunderbird emails to PST, preferably one that maintains folder structure and email integrity?
