Last year I had exported mailbox data from Outlook 2016 in .pst file format. Recently I remember and found the PST file in my Windows PC. I thought of getting access the data in Mozilla Thunderbird. So I found various ways to import PST to Thunderbird client. However, my search got failed, as Thunderbird doesn't have any option to import PST file. I found this article [https://www.adviksoft.com/blog/open-pst-file-in-thunderbird-with-attachments/ https://www.adviksoft.com/blog/open-pst-file-in-thunderbird-with-attachments/] The manual solution is quite complicated but the alternate solution is paid. Is there any other way to open Outlook PST file in Thunderbird? Any suggestion please?
