Our company has a main mail server. An exchange sits in our office which pulls mails from mail server. we use outlook to connect to our office exchange server and send/receive emails.
Now, the problem is, the exchange server is not leaving a copy on our main mail server. It is just pulling all mails in the mail server and storing locally.
Is there any way to set at exchange/mailbox level to restrict the exchange server to leave a copy of message on the main mail server?
