Does this happen with all messages, or just some, or one?

Did/do the messages get into the Trash because you told Thunderbird to delete it/them? Or was it due to a message filter or junk filtering?

more options

It happens with all messages that I try to move from Trash to the Inbox. The messages were first placed in Trash by a all of the mechanisms you mentioned. .

Please confirm: Is the 'Trash' folder a subscribed imap mail account folder on the same imap mail account as 'Inbox'?

Are you using Online mode?

What method are you using to 'move' the emails from Trash to Inbox? eg:

  1. right click on selected deleted message and select 'Move to' > 'mail account name' > 'Inbox'
  2. drag and drop selected email from trash to Inbox?

Thanks for your attention to this matter. My answer to the last 3 of your questions is YES. I don't what the Online Mode is, so don't know how to answer that question.

(This issue was first noticed a few weeks ago, perhaps arising from a recent Thunderbird software update.)

Check the Junk settings in the program options:

Program menu bar: Tools: Options: Security section: Junk tab Or if you use the "three bar" menu button on the top right: Options: Options: Security section: Junk tab

You will see what I show in my screenshot below.

Make sure that When I mark messages as junk is set to Move them to the account's "Junk" folder.

It could be that Thunderbird is thinking that these messages are junk, and if that option is set to delete them, your situation can happen.

The settings were already established as you recommended,

Restart the operating system (Windows or OSX), in Safe Mode with Networking. This loads only the very basics needed to start your computer while enabling an Internet connection. Click on your operating system for instructions on how to start in safe mode: Windows 10, Windows 8, Windows 7, Windows Vista, Windows XP, OSX.

Then see if Thunderbird works better. If it does, then another program or process is interfering with Thunderbird when Windows is running normally. Likely your anti-virus.
