Hi, Hoping someone can help. [rather a long story sorry] I have been using Thunderbird for a long time and was working OK until last week, then suddenly I can no longer log in, after a lot of hours on telstra help[which was no help] except to say that my bigpond.com was linked to my ex-partners account which was opened probably 20 yrs ago, i never remember having a password, and T/B was asking for that, in the end I went to a Telstra Shop and got my ex to be there as well as they couldn't do anything without him being there. Everything seemed to be going fine and got the bigpond account in my name with a new password, I even got them to help me install a mail program on my phone through gmail.....all good got some emails. On arriving home very relieved switched on my computer and downloaded some mail, then wanted to download TB on my phone which I did and tried to set it up, but couldn't get it to work......now I'm not sure what's wrong but read about having to have the correct server address and port number as I wanted to be able to sync from mobile to desktop and vice versa......so now I don't know which server and port number are correct.....so to cut the long story short I'm hoping someone can help with setup and server and Port numbers for old bigpond accounts and if they are are same on Mobile and Computer. Thanks if you read to the end :-) Sandra
