Hello. After having fixed the connection to Outlook a month or so ago, things have gone wrong again with Outlook connection. I now cannot send or receive any emails on Thunderbird. When I try, I get the message saying that Outlook's certificate has been rejected (I think). I tried clicking on "Get Certificate", but nothing happens. Does anyone have any suggestions, please? Thanks!
