I currently have an issue on a mailbox.
Mailbox 1 - can see all the mail from everyone (this is the shared account)
Mailbox 2 - Can see all the mail apart from 1 person.
I have checked the spam list and this user is not on there, i have also checked any rules and filters, i can not find anything anywhere on the net regarding this issue.
Please ask more questions if you require clarification.
