In the Folder Pane....'Local Folders' is an account created by default. It is usually listed at the Bottom below all your other mail accounts. But that depends - have you set up a load of pop accounts as deferred accounts so they use 'Local Folders' as their set of folders ? Have you set up 'Local Folders' as the default account in 'Account Settings' ?

Basically, I have no idea what your personal Folder Pane looks like and no idea what you mean by 'to view the folders below Local Folders'. You could have a view option which alters what you are seeing. I do not know whether you are using View > Folders > All or whether you have selected any of the other options eg: Unified

Pleae post an image of your Folder Pane and put a marker on image pointing to what you call 'folders below Local Folders'

Thank you for a list of TB's shortcuts.

All my emails are in IMAP format, not multiple POP accounts. All my TB emails initially went to my TB inbox. Also I have not setup 'Local Folders' as the default account in 'Account Settings'.

I don't know what the area "below the Local Folders" is called so I have used that description. In the uploaded image from W10 is a portion of that area. If you know what that area is called, could you please inform me?

In W10 and prior versions TB had this area. In W10, right clicking Local Folders allowed new Folders to be created and a few emails from Inbox were copied/moved to those folders. In effect, this was a way of saving those emails.

I presume that this continues in W11, but so far have not been able to find it.

I have been asking about this area since it contains many emails that have been saved and cannot be replicated.
