User Query :\u00a0<\/strong>Hi,\u00a0<\/span>Is there a way to copy an old .pst archive to a Thunderbird account?<\/span><\/p>\r\n

I don’t want to upload all old emails to the server via IMAP, just to connect the emails to my account in Thunderbird so I can search them and leave them on the local machine.<\/span><\/p>\r\n

I know there is an import function, but I’m not sure if it copies them to the server or just to my local folder.<\/span>
<\/span>Is there any secure and reliable way to import PST files to Thunderbird without any data loss? <\/span><\/strong><\/p>\r\n<\/div>\r\n

\r\n
