Need to import mail from Outlook 2007 located on anothe computer
I have a new Windows 11 PC and have installed Thunderbird (64bit). My current email is via my ISP who have outsourced their email to Gmail - I am using IMAP. This setup is in Outlook 2007 on my old PC. I have setup Thunderbird to obtain all of my current email from the IMAP server at Gmail. This went successfully.
I now wish to move all of my off-line stored emails from this old Outlook installation and also my calendar. When I started the import process on Thunderbird and selected Outlook as a source all I really wanted to do was to find out what Thunderbird would ask for in the way of files containing my data. But, as per other postings that I have found on this site it came up with the "No profile found" .
However Outlook is NOT installed on the Windows 11 computer and nor have I created any pst files or any other files and moved them to the Windows 11 PC. So the 32bit vs 64bit answer does not yet apply to my situation.
So what process should I follow to move my data from the old Outlook 32bit installation on my old Windows 10 PC to the new Thunderbird 64bit setup?
Thanks for any advice
