Hi I use a PC running Windows 10. I created a new email adress using Outlook. All is displayed correctly in Outlook.live (subir inbox, outbox, draft, archive, etc) Now when I try to add the same account (email adress) in Thunderbird PC (last release), the system found well my data (IMAP, SMTP...), but is unable to display submenus. Only the Inbox appears. The setup is not complete and I have no error. But in Thunderbird I received a notification stating something about the authentication of that new email adress but I have no access to the full notification (when I clic on the notification it disappears). I deleted this account (data and message) in Thunderbird, closed Thunderbird, and created it again, same result. Only the subdir inbox appears. In Outlook.live this account works fine, I can send and receive emails. In Thunderbird I can also send emails but I do not receive them while they are received in Outlook.live. So it seems that there an issue in Thunderbird And I have no opportunity to add the account manually. Any suggestion to solve this issue ?
