My TB has stopped working. Win 8.1

more options

My OS is Win 8.1. My TB is 24.4. It worked fine yesterday 03-18-2014, but today it just runs and runs, no errors, no retrieval of email. I don't know what to look for or how to correct this extreme problem and have had to work with another email program that is not nearly as good as TB.

I have not added (as far as I know) any other program. There have been no notices of invasions to my OS.

I am not familiar with Win 8.1 protocols.

Please let me know exactly what you are expecting me to do. I will really appreciate any help. Regards

I want you to exactly follow the instructions posted previously, i.e. start *Windows* in safe mode with networking enabled. Still in Windows safe mode, start Thunderbird in safe mode.

Report back what happens.

please open a new thread for your problem.

Sorry. Maybe my explanation was confusing. I started windows 8.1 Pro x64 in Safe mode with networking and started Thunderbird while windows was in safe mode and it had the same problem as before. Thanks

Also "christ1" asked me to open a new thread for this problem. I will do that right away. I am also talking about the same problem in this thread:

No, I asked Scooter to open a new thread.

Ohhh. Sorry about that. I thought that you only did a confusion.

No one has asked, so I will. Can you please post the Troubleshooting information from your help menu. It does sound to me like an ISP or Mail provider issue. ATT/Yahoo regularly have a couple of days where they do not work and then it miraculously starts again. Neither ATT or Yahoo appear interested in their customers difficulties as they want everyone on an add laden web mail page.

We have a single gmail account here. Periodically it stops working for you but not the millions of other gmail /Thunderbird users. What could have changed.

I can only thing of a few of things that could cause suchg an issue without modifying anything consciously.

  1. You elected to use Google two factor authentication and did not get a Thunderbird password as required.
  2. Your computer received an update either from Microsoft or one of your software suppliers that causes an issue.
  3. Your internet connection is troubled by outages at random.
  4. Windows defender strikes again.
  5. Bit defender strikes again.

Note that setting windows to not update it like buying a gun for defense and not buying bullets. Security software is part of your protection not the be all and end all.

There are no updates ever in my windows 8.1. the options for updates was set up from the beginning to not receive any updates. Thunderbird it won't work with any email, not even gmail. for more than 2 week now, it won't even let me add any email account, it does not matter if is gmail, aol, or any other. Thunderbird it won't connect to any server, not even to ghandi or the other one that comes as default when you try to add a email account. the internet connection has no problems. i have tried several different internet connections,

Anyone who is still following this or may stumble upon it, and is having similar problems;-

Try looking for a "Scan SSL" setting in your security software (McAfee, Bitdefender, etc), and turning this off AS WELL AS ensuring Thunderbird has been added to both Windows firewall and your security software firewalls (or disabling Windows firewall and just using your security software firewall).

I accidentally stumbled on commentary regarding potential problems with SSL scanning and POP3 email servers, and turning off "Scan SSL" fixed my problem of being able to send but not retrieve emails using Thunderbird + Windows 8.1 + Bitdefender on a POP3 email server that will not be changing to more "modern" connection protocols any time soon.

In Bitdefender, "Scan SLL" can be found in Privacy Control Settings under the Antiphishing tab.

Unfortunately I can not explain why this worked as this is beyond my area of expertise, but it has worked for me.

For information;- Windows7 (latest update) + Bitdefender Total Security (latest update) + Thunderbird (lastest update) accessing a POP3 email server = working fine with Scan SSL turned ON.

Windows 8.1 (latest update) + Bitdefender Total Security (latest update) + Thunderbird (lastest update) accessing a POP3 email server = able to send but not receive emails until turning off Scan SSL in Bitdefender.

Oh, and no more starting or running in Windows Safe Mode to retrieve my emails!!

And just to be absolutely clear, I do NOT suspect or believe this is a Thunderbird problem. Thunderbird appears to be the "innocent victim" of latest windows and security software that do not appear to work well together in all situations an settings.

Good luck!

Hello. At this time my Thunderbird works. I changed Bitdefender with AVG and maybe because of this move Thunderbird started working again although AVG is giving me hard time. Is not an antivirus that you will want to use if you don't have a lot of patience. A lot of other problems showed up because of AVG. But a lot. Bitdefender is a king comparing with the AVG which is not user friendly at all. Anyway, for me Thunderbird didn't do anything before. I was using IMAP not Pop3 but that was not the reason for not working. Thank you for your advise regarding the "Scan SSL" setting as I am intend to use Bitdefender again.
