This is the second time this has happened. I clicked the Get Messages button in Thunderbird and it said there were no messages - I knew there had to be some. So I shut down Thunderbird and restarted it. Again tried Get Messages. This time a notification popped up saying something about not being able to access the inbox because it was being used by something else. I clicked OK in that notification and then it immediately started downloading messages, counting up to 27 - everything looked normal. However, nothing appeared in the inbox. Unfortunately, I had the pop3 setup to delete messages from the server once downloaded (I have since changed that), so when I checked the server, there was nothing there. So it appears that everything worked as expected except that the messages did not appear in the inbox. I checked other folders and do not see them. Where could they have gone? And more importantly, is there any chance I can get them? Regards, Dave
