(Thunderbird :: General, defect)

Description

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:10.0.2) Gecko/20100101 Firefox/10.0.2

Steps to reproduce:

We upgraded Thunderbird from 9 to 10 and even now tried version 11, same issue


Actual results:

We can no longer connect to our Cisco Unity Voicemail Account. When we click on the Inbox, it just keeps spinning. 


Expected results:

We were able to connect and check emails in our voicemail account in Thunderbird 9 without any issues.

Are you running Firewalls or Anti-virus solutions on your desktops ?

Comment 2

[Network Admins]

Yes, we are. But, I just turned them off and I am still unable to connect and we haven't changed anything in our Anti-virus settings. Even right now, if I downgrade to version 9, the account works.

Turning the Firewall off doesn't matter, downgrading also doesn't matter if the Firewall blocks the access because of a changed Application.exe (Checksum mismatch).
Turning the Firewall off doesn't remove the Firewall driver from the system.

You have to remove Thunderbird.exe from the Firewall configuration and add it again.

If I understood you correctly, I completely removed Thunderbird from the system and re-installed Thunderbird 11 again. But, only the mail Email account still works, but the voicemail account doesn't work. If the firewall was the culprit, then I would suspect that both accounts would not work.

>If the firewall was the culprit, then I would suspect that both accounts would not work.

That is correct but you didn't mention that other Accounts are working.

Do you use IMAP, IMAP over SSL, pop3 or pop3 over SSL ?

Comment 6

[Network Admins]

Oh I am sorry. I thought I said it. We use IMAP over SSL. The account which works also uses IMAP over SSL.

Comment 7

I assume that the working Account and the not working Account use different servers.
In that case try this:
close Thunderbird, open a commandline prompt (windows: start/run/cmd), use the command "set NSS_SSL_CBC_RANDOM_IV=0" (without the quotes), change to the thunderbird directory from within this commandline prompt and start Firefox -> "cd \Program Files\Mozilla Thunderbird" , "thunderbird.exe".

Comment 8

Yes, we use different servers.

I tried it and it worked. :) YAY!!!!

But, my happiness was short-lived. If I close Thunderbird and start it again, then it goes back to spinning again. :(

Any other way, we can make it to work permanently?

I assume that you have restarted Thunderbird not from the commandline with the set environment variable but rather via the normal way.

The bug is in your Voicemail server.
All major browser vendors (Microsoft, Mozilla, Opera) changed something in the ssl communication to fix a general SSL security issue. This change is legal but wasn't used before. The SSL server seems to be broken with this legal change in the SSL communication.

A permanent fix would be an update of your voidemail server.

Workaround:
set this variable "NSS_SSL_CBC_RANDOM_IV" to the value "0" as system environment variable in windows.
Use a search engine and you will find several links that explain how to do that.
Note: This will also disable this security fix in Firefox but IMO there is basically no risk if you do that.
