Send several emails to the 2 accounts 2.check they are well received on the mail server (webmail server) 3.launch Thunderbird : Actual Results: the new emails sent to acc1 are well received in all cases - at launch, on global request (get all), and on specific request (get acc1) - whereas the emails sent to acc2 are not always received at launch and on global request, but are well received each time using the specific request (get acc2). Expected Results: get all the new emails of all the email accounts on automatic request and on global request (get all)
