I have one user (User A) who is getting email from another user (User B) in the spam folder. All users are running Outlook 2007 and we are on an Exchange 2010 mail server. The email in question is sent internally. Only User A is receiving the email from User B in the spam folder. Everyone else receiving email from User B is receiving it just fine. User A is receiving email from other users in the company fine as well.
Can anyone help point me in the right direction? Is this an Outlook or an Exchange issue?
