====== Automatically sync folders from Outlook 365 in Thunderbird ======
Without this, you need to select each folder separately to get new emails. This will automatically sync them.

Go to Thunderbird Preferences and search for //"Config Editor"//. Find the ''mail.server.default.check_all_folders_for_new'' setting and double click it to set it to true.
