I need to get access to a series of emails sent 3rd/4th week of Feb. I had been using Thunderbird but that computer died. I have a new one with THunderbird, but the messages only go back to June or so. When I go into webmail, and click on "old-messages", it says "Internal Server Error". I can't get Thunderbird to download the old-messages folder. I have it set to save all emails and there are approx. 7k messages in old-messages so I know it is there I think... I just can't get at them.
Any strategies / ideas welcome.
