I have such a problem: There are 2 mail addresses in exchange (name1@domain.com & name2@domain.com). The first address was forwarded to the second. After we deleted a user account in AD, connected with name1@domain.com. A few month later we created a new user account with the same address name1@domain.com. And strangely it is forwarding to name2@domain.com, although we didn't set any forwarding options now. Where can be the problem? User profiles are new, using Get-TransportRule returns an empty string. Any ideas?
