Any one else having problems connecting to IMAP Servers with Thunderbird 16.0.1?

Question

Recently I've had problems connected to an Exchange server configured with IMAP. The configuration used to work until the system updated to 16.0.1. - now I get: "Connection to Server XXX timed out error" each time I connect.

Although I sit behind a proxy, Thunderbird has no problems finding extensions or add-ons (which suggests that the internet works) and I have tested the IMAP server with an earlier version of Thunderbird (3.x) on Windows and got lots of e-mail which suggest the server works.

Is anyone else having this problem or if not are there any tips for generating more information on the situation?

Answer 1

So to answer my own question. After more testing I can connect to the IMAP server with almost anything except the machine in question behind the proxy...

So it looks like a local configuration or network problem rather than a problem with Thunderbird.

Answer 2

To help Answer your question, Oddly enough it helps to set the system proxy, but then in Thunderbird itself go to:

Edit> Preferences> Advanced> Network> Connections> and set Thunderbird to use NO PROXY

For some reason... it works... here is the link to where I found it
