I am using thunderbird as a "backup" tool to download all my e-mails from googlemail. I'm using POP3 and I'm only downloading e-mails and not trying to send e-mails through thunderbird. So I did get an e-mail from google which asked me to allow the access for thunderbird. DONE And I did setup the googlemail account for the POP3 delivery. DONE (maybe with misstakes?) Until now thunderbird did a great job downloading round about 24.000 e-mails .. starting in the year 2007 until July 2012. While doing so I got a message that the folder is full ... so I started doing subfolders - one for each year .. which fixed the overload problem. After this thunderbird went on downloading my e-mails but only until July 2012. Now if I start the software it checks for new e-mails but it always tells me "no new e-mails available" ... so all e-mails of the years 2013,2014 and even the recent ones of 2015 will not show in thunderbird. Is anyone able to tell me why? Thanks and cheers, Markus
