Disable email scanning in your anti virus and reboot your computer to be sure it is disabled and try again.

It sounds like there are to many requests to the server to quickly. But that would not be the case. Surly they have a powerful cluster of servers, not an iPhone 4 on the other end of the wire.

Thanks for your advice. I did disable my anti-virus protection but when I rebooted my computer the protection was restored. Can you advise me on how to disable "email scanning"? I'm running Windows Defender. Thanks.

Could you please do the following:

1. Open the menu > Help > Troubleshooting Information, then click Copy text to Clipboard.
2. Go to https://pastebin.com and paste the info from your Troubleshooting Information page, then copy the resulting URL.
3. Open a reply to this post, and paste the link to your troubleshooting information.

Next, we'll need you to provide answers to the following question:

• Does Thunderbird work in Thunderbird Safe mode?
• Who is the internet provider?

I'll do what you've asked in a few minutes. I'm repairing the Inbox folder right now and that takes a while because there are tons of messages there. It's actually my wife's account that's not working properly. She uses pop3. I use IMAP and my account works fine.

I was checking the Internet to look for other solutions to this problem and I came across some help you provided to another Thunderbird user. You suggested that he(she) find the last message that was successfully downloaded and then delete the next one. I did that and I deleted all the messages in my wife's spam folder. That solved the problem for the other person yoiu were helping but it didn't solve the problem for me.

I haven't tried using Thunderbird in safe mode. I'll figure out how to do that and give it a try.

We're using AOL. We used to use Verizon. They sold their email business to AOL and the only way to keep our old email addresses was to move to AOL.

I'm now running Thunderbird in safe mode.

When the program restarted it tried to download messages to our Inboxes. I got this error message when the program was trying to download messages to my wife's Inbox: "The DELE command did not succeed. Error marking a message as deleted. Mail server pop.verizon.net responded: Too many requests."

Try this; Move all good emails from 'Inbox' into other suitable folders for storage.

Right click on Inbox folder and select 'Compact'.

click on 'Get Messages'

Thanks for your suggestion. I thought of this but I was reluctant to try it because my wife has so many messages in her Inbox but I'm going to give it a try now. If this doesn't work I'm going to try moving all her messages to local folders, delete her account and set up a new account for her. I'll let you know how things turn out.
