Hey all, I'm wondering whether somebody ultimately goofed. We've got a new Exchange server up ... running 2016 with Outlook 2016. On premise, and with autodiscover configured. When I opt to use my credentials, it behaves and everything like an Exchange server normally does ... but when I look in my accounts it shows as IMAP rather than Exchange ... I have all of my inbox and what not folders under an Outlook folder with the name of my email address like normal, but then there is this other set of folders under that with an empty inbox and outbox, but a full contacts,, calendars, and notes folder, under the name "My Outlook Datafile (1)". I can send,, receive, add events to the calendar, add contacts to the server, and everything, but it's bothering me that I've got a split configuration. Thought Exchange used MAPI by default? I'm definitely suspecting somebody goofed since my off premise other email account using Office 365 (this one) doesn't do this. Thoughts would be great. We do have full AD implemented as well, though my workstation doesn't have a current connection to it since we're still messing with domain structures if that matters. Needless to say, this is driving me five kinds of bonkers.
