Can't connect to Exchange 2003 IMAP after upgrading from 31.7 to 38.5.1
I can connect to other IMAP servers and can connect to this one from other clients as I could under 31.7.
The status bar says checking mail server capabilities .. but never gets any further and doesn't ask me for my password.
I did try setting network.auth.force-generic-ntlm-v1 true without success.
I did raise this when I first went to 38.0.1, I guess it hasn't been fixed yet. How can I revert to 31.7 ?

2003 exchange I think has no idea of modern security. Are you using SSL/TLs? If so disable the use in both Thunderbird and exchange.
Yes, I am using SSL/TLS. Changing Thunderbird not to use SSL/TLS makes no difference. I cannot change Exchange because I am but one client among many and the others are working fine with these settings.
Is the server up to SP 2 has knowldge base patch KB968730 been applied to give the server sha256 capabilities.
This is one time I
think Outlook is probably working because it it not up to the current security standards.
You might also try installing this firefox add-on into Thunderbird. https://addons.mozilla.org/en-US/firefox/addon/disable-dhe/
In Thunderbird on the toolbar 
then 
In the wheel icon on the far right click the menu and select to install from file and select the XPI file I linked to earlier once you have downloaded it of course.
I have tried the disable DHE add-on without success.
I am trying to find out which patches have been applied to the server...
Other clients that can connect to this server include iOS and android IMAP clients.

yeah, but they are pretty simple
