Since the beginning of July (latest update) Thunderbird cannot download any new emails. When I try to get new messages, it seems to connect to my optusnet email account, then it will say Downloading message 1 of 27 and after about a minute it just disappears. Then it says no messages to download. The little blue progress bar also disappears. I have checked the server settings. I am using Pop Mail Server, server name is mail.optusnet.com.au, user name is my email address, Port is 995, Connection is SSL/TLS and Authentication is Normal password. I have tried turning off Firewall and Antivirus and still not coming through. Its like it connects and it can see the emails but it cant pull them across. I am not a computer person. I dont know how to check any more than this. Please can someone help me. I have been using Thunderbird for many years and this issue has happened in the past but always resolved itself. TIA
