We need to "point" all users to an alternate Public Folder server and need info on how/when that change is processed by Outlook clients. We tell the message stores what server to direct users to for public folder references. When you fire up Outlook you get a reference. Last time we tried to make a "smooth" transition by doing a few mail stores at a time. However, since people stare at these folders every second, the delay between users was painful for them. So, this time, we want to move all users at the same time. What I'm unclear on is WHEN that change takes effect. When Outlook starts, certainly. But only at startup? Will it pick up a public folder reference change in the middle of operations? If your connection sits idle, or your connection to PFs goes idle, will it check again? I have no idea! Any assistance would be appreciated.
