If it keeps asking for mail account password then it sounds like your passwords are not being saved.

When you enter the requested password, did you select the checkbox to remember password before clicking on OK?

Do you have passwords saved in Thunderbird ?

• Settings > Privacy & Security
• Scroll to Passwords section
• click on 'Saved Passwords'
• Is anything displaying in this area?
• If yes, click on 'Show Passwords'
• If you see a windows security pop up window asking for password - when you start up computer you get asked to logon to your User Account - that is the password you need to enter.

If there are no passwords - that area is empty - and you have been selecting the checkbox to Remember Password, then it's possible you have an Anti-Virus program OR a clean up software program like CCleaner or WiseCleaner etc which has been deleting the passwords file. You are advised to make your Thunderbird profile exempt from access by those programs as they can cause a nuisance.

Please report back telling us what you discover in the saved passwords section and also whether you have clean up programs allowed to access your Thunderbird profile folder.

Thank you for the reply. I do not have any software cleaner, I do have antivirus software from Norton, but I have had that for many months and have had no issues with this until now. The email client again required me to sign in with the password before I could view this message.

When I booted up the computer this morning, I did have to sign in again to the Thunderbird email client in order to read my emails.

Also, the machine does not even have to go to sleep mode for me to have to sign in to check my email. It is getting frustrating.

Who is the mail provider? And what authentication method is specified for the account?

Windstream/Kinetic is the internet provider. As I noted, this is a recent issue and I am experiencing it on two computers, a desktop and a laptop. Both equipped with Thunderbird email program. I have had the desktop for nearly 9 years and the laptop is 2 years old. I have always used Thunderbird during that time. The only change in my machines was the addition of a new version of Norton antivirus that I installed 8 or 9 months ago.

I have not made any other changes to my equipment or programs. I do a disk clean up about once a month and the defrag program runs on a regular schedule.

Regarding an earlier suggestion, I logged into Thunderbird using the password, went to the Settings page to check passwords, and I had to log into Thunderbird, again to check to see what password is listed.

It is getting frustrating since I have made no changes to my computer, not added programs or apps, and this just suddenly appeared.

Thanks for the continued directions being provided.

re :Regarding an earlier suggestion, I logged into Thunderbird using the password, went to the Settings page to check passwords, and I had to log into Thunderbird, again to check to see what password is listed.

I'm presuming the passwords were saved. But...you said you had to log into Thunderbird again to check to see password.

It's normal to need to logon to see saved passwords, but the password to logon to mail accounts is not the same password you use to get access to saved passwords ...unless you are not talking about mail account passwords.

I'm now wondering if you are not talking about logging on to mail accounts - I'm wondering if you are being asked for a 'Primary Password'.

Have you set up Thunderbird to use 'Primary Password' ? It would be shown here:

• Settings > Privacy & Security
• Scroll down to 'Passwords' section.
• Is this checkbox selected : 'Use a Primary Password' ?

if yes then you will be asked to logon using the 'primary password' at the start of each session and also you would be asked to enter the 'primary password' when accessing saved passwords.

Is there a reason why you have set up to use a 'Primary Password' - which should be a unique password not a mail account password or a User Account password. Normally you would set up a Primary Password only if you share your computer and your User Account with other people and you want additional protection from prying eyes to stop them seeing your actual mail account passwords.

I too am having almost exactly the same problem going on for next to a month from my ISP Windstream Kinetic . However my issue is not that I cannot send and receive email initially, but that while viewing my email , after opening up my email client "Thunderbird" I get this nuisance pop-up on occasion that unless you cancel it , you won't be able to download your email and the pop-up wont go away until you cancel it . Then later it will pop-up again. I have tried entering the password instead of canceling but that does not work either . The pop-up says "Login to server.... failed" and I have three choices to Retry - Enter New Password , Cancel . I have looked in my Thunderbird settings and see my password so they are being saved .

Todd-Hall, my desktop did have the Primary Password box checked. I went in and unchecked it. No affect other than no more Popup asking for the primary password. My desktop stopped all email activity two days ago. Even when I entered the password, it does not download email. My laptop, which I am using now, still required I enter my email password, not the Primary Password in order to download new emails. And as I said earlier, my email work normally on my iPhone.

I am not all that tech savvy, enough to get by, but this seems beyond my skill set.

Teamoklahoma, I too have Windstream/Kinetic, which is a pathetic ISP.

So I am still looking for assistance in getting this corrected.
