Why doesn't ThunderBird show more than 50 attachments?

Question

Email

I encountered a problem in ThunderBird, it does not display attachments with more than 50, that is, it shows the first 50.
In the settings of the mail account, it is indicated not to store messages locally.

if you enable local storage, then new messages with attachments of more than 50 are already displayed correctly.

Answer 1

If it is shown locally and not shown remotely, then the limitation is most likely not on the ThunderBird side, but on the IMAP server side.
