I tried to import using 2 différent tools (zoho migration tool and  https://ssl0.ovh.net/fr/imapcopy/) which work very well with other email providers, but with both tools, there's a restriction when I try to import my folders.

It imports the 2 firsts level, but not 3+ levels, for example :

folder1

folder1/subfolder1

but not folder1/subfolder1/anotherfolder

The importation looses all affiliation to the «anotherfolder» and all e-mails are classified in folder1/subfolder1

This is very annoying, because I lost all my folders organization when I try to import... :(

Is there a way to preserve this tree ?

Best regards,

C.
