Keeping messages copy on server no matter they are deleted on clients (outlook or other)

If we want to keep messages on server no matter what configuration is on clients (we use outlook) e.g. if we delete messages or checked is option that messages will be deleted from server after [xx] days (where xx is variable...) is it enough to use IMAP protocol?

I found out next statement:
For IMAP email accounts - messages will always be left on the server until deleted.

from here its not clear where delete happens, on server or can it be deleted from client (e.g. option delete from server after xx days is enabled...).

We want to always keep messages on server for control reasons, until they are only deleted from server. How can we acomplish this?
