Please provide more detail on exactly your status and I will attempt to assist. Thank you.

David Thank you very much for the reply.

Version 128.0.1 OS Windows 11

After the update, the software suddenly became slow.

At the same time, the body of the email is not displayed and new receipts are no longer possible.

Inbox -> Properties -> Repair Folder
I tried to solve the problem by the above process.

Then, three years of emails from 2021-2024 disappeared.
Instead, the software works better and new emails can be received.

Did the e-mails disappear? Are they hidden somewhere?
Is it possible to recover the lost 3 years of emails?

Is this a POP account? My fear is they may be lost.

Thank you, David.

Yes, POP account.

I fear it's lost, unless you have a copy on that external drive.

I have the same problem. After Thunderbird updated to 128, I lost emails from 2021-2024. I also have a POP account. This only happened in the INBOX. All of my other folders do have emails from those years.

This morning while I was reviewing my emails from the inbox something happened to the emails. I could see the subject lines but when I click on the email the body of the email was all blank. All the emails from the last few days also showed a blank screen in the email body. I went into the Inbox --> Properties --> Repair and it ended up losing all my emails from today till July 19, 2023. Lost more than 1 years worth of emails from the inbox. Any way to recover the lost emails ? Please help. Thank you.

Yes, that's the exact thing that happened to mine. When I search my emails, the recent ones show up but no content - just the subject lines. When I clear the search, what's in the inbox is mail up to Sept 2020 and then yesterday's. I tried properties - repair but that didn't work.

Same happened to me, sadly I think there is no chance to get it back. Nebula is killing our mails.
