I have 2 PC's, one at home when I work from home and one at work when I'm at the office. For my work emails, I have thunderbird installed on both machines with the same settings (POP mail server). The problem I have is that any emails I send or sometimes receive from one location do not appear at the other. For example, if I send an email from home, it doesn't show in my sent items at the office (and vice versa). Also, some emails that I receive whilst at the office do not show up at home (and vice versa). I've scoured the internet for a solution but haven't had any luck finding an answer to my exact issue. The last thing I tried to do was to delete "global-messages-db.sqlite" and re-index, as said to do on this page https://www.systoolsgroup.com/updates/thunderbird-not-downloading-new-messages/amp/ but that doesn't seem to have fixed anything =( Any help would be greatly appreciated. Thank you.
