“Hi, I am a non-tech user, and recently my friend upgraded to Thunderbird. No, she has migrated a few emails from her previous AOL account, but still, a lot of data remains untransferred. I guess Thunderbird default doesn’t support them, that’s why they aren’t moved, or maybe the size of the data is too large. The server setting is set to POP3 if it helps anyway. Can you suggest an effective solution to import the entire mailbox data without any missing or lost files and structure?”
