Hi @Luca Procentese ,
Welcome to our forum!
In the old Outlook it was possible to move mail folders with a simple drag and drop, in the new Outlook this feature is not going, does it still need to be implemented?
Based on my test in New Outlook, I've found that we can drag and drop one folder into a subfolder of another, but not move locations between root folders, which is different from Legacy Outlook.
Is the same for signatures?
As i know, we can create and use signatures normally in New Outlook, what are you referring to specific signature-related problems?
Is there no way to organize multiple mail accounts and signatures?
As i know, we can add multiple Exchange type accounts either associated with work/school or a Microsoft free account (Outlook.com/Hotmail.com/Live.com) and Gmail accounts in New Outlook. Please check the account you can't add is included in the below limitation:
