We have 2 Exchange servers, one Exchange 2003 and one 2010. We are migrating from 2003 to 2010 and this has been largely painless, but we have a niggly problem I can't figure out and the documentation isn't the clearest thing in the world.
When a mailbox moves from Exchange 2003 to Exchange 2010, and the client is Outlook 2007 or greater, the Out of Office dialog changes to include internal and external OOF message options. I understand the reasons behind two separate messages, but it does not work well for us (people forget to change both messages, complain about having to set the same message twice etc.) and I want it back to how it functioned in Exchange 2003 - a single OOF message which is sent to both internal and external senders.
I cannot for the life of me find any options in the Exchange Management Console, and I can't see any PowerShell-only options to make it go back to Exchange 2003 style functionality. Does such an option exist, and if so where on earth is it?
