One of our users is experiencing an issue where internal domain senders mail are moved automatically to his junk folder. This does not apply for external senders, which are kept in his inbox folder.
Tried moving mail back to his inbox, but ca. 15 seconds they are moved to his junk folder again.
Checked his Outlook, OWA and exchange(get-inboxrule), but he has absolutely no rules.
He uses Outlook 2010 on a 2008R2 terminal server.
We are using Exchange 2010, 2008R2.
Any ideas on what might be the cause ?
