Hi, I have been using Thunderbird with both IMAP and pop3 settings(downloaded and saved to a local file). My PC(Win7) broke down so I had to migrate data into new PC(Win10), but I can't find the correct way. This thread (https://support.mozilla.org/en-US/questions/1082172) suggests migrating old profile into new pc, then by using profile manager (with creating new profile using old profile folder) the old email can be accessible. I tried this but this only produces new profile with renewed IMAP settings - no old pop email data. I've been using thunderbird for 7 years + with multiple pop3 email accounts, but the profile folder only weighs 200MB, so my hunch is that the pop3 data is stored somewhere? Any help is appreciated.
