Check for new mail in all folders

Hi there;

I have 5 email accounts in my Thunderbird, some of them have filter rules on the server, I mean not on the client but at the email service itself.

And TB does not go thru all the forders to search for new mail, only the inbox and the spam.

It is only when I click on each folder or sub-folder, that it checks for it,

So, how can I set it up so that it goes thru all the folders when checking for new mail?

This is not my language, sorry if this feels redundant.


In the folder right-click menu, Properties, there is a checkbox ‘When getting new messages for this account, always check this folder’.

Found it,

I did not know that was in there, Thx.
