I have an issue. Out of office is replying to every email sent when enabled. This is only happening to 2 users, they have different OS's, and different versions of Outlook. They have no client side rules, and the only rule listed server side seems to be a default rule. The rule is listed below. One user was recently moved to a new computer, one user has had his computer for more than a year. If i close outlook and use the OWA to turn on Out of Office, I have the same results. No one else in the organization is affected. This is Exchange 2013 in a DAG setup, 4 servers total. The two users are in the same OU, but the vast majority of users are in that OU. They do have some groups in common, I can't find a group that only these two users belong to. There are at least 10 users in each group they are members of. I'm at a loss here. Where else should i be looking?
Server side rule: Clear categories on mail (...
