Lack of functions and issues with New Outlook

Hello,
we have tested New Outlook in our company and we noticed lot of issues and lack of functions in New Outlook, can you consider to add this functions and fix issues?

*In shared mailboxes, my signature is not added, but the signature of another person who also has a signature set.
*A message sent from a shared mailbox is saved in my mailbox in the sent folder, not in the shared mailbox
*Inability to print/save several emails to PDF at once. After selecting several emails, the CTRL+P shortcut does not work; the print function on the ribbon is grayed out - this is very important, because we have people that have to print a lot of e-mails and click one by one is such a waste of time.

Messages with attachments:

* unable to drag the attachment to a folder on the computer (saving only via the download function)
* attachment preview opens in a new window (in the old Outlook, in the same one)|
* attachments in PDF format - in the old version, after double-clicking, they opened in Adobe Acrobat Reader, here, after double-clicking, nothing happens
* after downloading Excel files, macros do not work (in this file)
