lost emails

This is the Thunderbird for desktop computers forum. You would be best off asking your question in the Thunderbird for Android forum where its experts can be found:

How about I just move the post to the correct forum.

Yes please

Hi Anthony

Reports of inbox content disappearing is thankfully not something common on TB Android. I've only seen a single report of something similar in many years, here. My Google searches show reports related to the desktop version. Desktop and Android versions are distinct and don't share the same code base.

Thank being said, lets see what we can do to help.

I assume your account is connecting to your mail provider using Imap? (You mention Spam and Archive folders which pop connections don't offer.)

1. Have you logged in using a browser to your providers webmail and confirmed if emails are missing or still present on the server?

2. Do you have any other email client (ex TB Desktop) where the same account connects via pop3? With pop3, emails are downloaded to the local device, then typically deleted from the server.

Since TB sync's the servers view when Imap is used, deletions on the server will be reflected in the mobile app. This is one possibility worth considering.

3. Are the emails missing from only a single account? 4. Do you use the Unified Inbox?

The more information you can provide about your configuration, the better chance we have to help you.
