Hi, my ISP has just changed its email server to an IMAP protocol which my OS does not support, they recommended that I install Monzila Thunderbird which did allow me to make contact with the new email server and allow download access to my emails. What I now need to do is import my past emails, contact and folder structure that I had in my previous email client which was Windows Live Mail 2012 in to Thunderbird 115.16.2 (which is the only version that I have found that works with my Windows 7 OS 64 bit). Please can you tell me how I can achieve the import as eveything I have tried on the Import menu pick in Thunderbird does not appear to work. Many thank for your support, Richard.
