Windows 10 Sync Comcast Email With Thunderbird

more options

Currently on this Windows 10, my Comcast Email is synced with Windows Mail, which Microsoft is going to do away with. It has little functionality and I want to replace it with Thunderbird. My new Thunderbird installation only imported eleven messages. I have to do a better job importing messages to Thunderbird. The ImportExportTools NG only imports from some downloaded location. Is there anything more direct that will import the Comcast email account? At least Windows Mail synced with the File Tree I established in my Comcast Account here on this Windows 10. However, Windows Mail lacks functionality. You know that file extension .eml? According to articles on this, that is the extension in which Windows stores Mail messages. A Search in File Explorer brings up no such extension. This is a real bare-bones version of Windows Mail since it has none of the features that these articles describe. On this network I have Thunderbird synced with Comcast Email on my Mac Monterey. I don't know why it worked there and not here on Windows 10.

Dave, Thanks; but I saw it before. That .eml extension does not turn up on this system. That addon I already explored. I thought maybe for Comcast, Thunderbird might require IMAP for more complete migration. Some of these articles don't even mention POP3.

I believe Windows Mail can export to pst format. There are a number of websites with info on how to convert pst to mbox and that would support Thunderbird directly. There are also some proprietary programs at $30 or so that do that. Not being familiar with Windows Mail, I can't offer more, but there are others on this forum with more experience there.

David, Thanks. I will look for that extension instead. Just now I posted to Comcast's forum. I suspect that I might have to use IMAP although Thunderbird on my Mac synced with POP3 and works fine. Export? In Windows Mail there is no such command, not in my Windows 10 version. They want everybody with the Mail app to use Outlook, which never had much security. With that you'll get messages from people you thought you'd blocked. Just now I added the Comcast email address, creating another account this time with IMAP. It imported 240 messages, about a year's worth. I guess that's as good as it gets. That's as many as the account inbox has in it now online. My suspicion about Thunderbird only syncing Comcast email with IMAP might be correct.

Whoa! I see something unexpected in this setup. For each time I imported my Comcast email address, there is no Sent folder, unless that appears when I send my first email from this address.
