Gmail?

No, IMAP my provider

IMAP is a TYPE of account. It is not a provider.

Thank you for your wisdom. I'm using IMAP account not POP. Gmail is not the only email service. It has nothing to do with Gmail.

My internet provider is not the issue. The latest TB upgrade seem to be the issue. Was working fine before. I'm using all TB default settings.

By the looks of it I'm not the only one with this issue. So please get on it before we run out if patience.

I only have 6000 emails to download. Feel sorry for the ones with 10 of thousands.

The first step to solving a problem is understanding the problem. A statement of "Thunderbird redownloading messages" is a starting point but isn't sufficient to understand the problem. This is why questions are being asked. If you are not up for questions, that's fine too.

I see you have an ego issue. Go help someone else.

Hi

We are all here to try to help you, but please appreciate that you have not given us a lot to go on.

To clarify, what happened before the emails started downloading again? Did you witness any kind of update or had you signed into your email account in Thunderbird again?
