About 2 years ago, DTS moved from using Exchange with Office 2000/XP to Novell Groupwise 6.5. The decision was due to the cost of upgrading Exchange to the 2003 version and the additional needed hardware and licenses. I really love the three pane layout of Outlook 2003 and later, but I found that with some upgrades to GroupWise, I could no longer use Outlook 2003 to communicate to with the GroupWise server. I was hoping Outlook 2007 would solve this. Unfortunately, I have only been able to get it to read messages so far, but I cannot get it to send mail. I am using GroupWise’s caching mode, so I might try to change back to the default client/server setup and see if that will work.
