- I downloaded the 2016 Exchange server eval – Download the latest version of Exchange. For more information, seeĀ Updates for Exchange Server.
- Ran the command to update AD Schema
- Manually syncd ad/o365 afterwards and hoped for the best.
It turns out that nothing changed for any users already syncd with office365, so id call that a success.
However, you will need to go in to the Azure ad sync tool on your DC and manually tell it what to export from AD to the cloud that is now new…. Such as the hide from address book attribute for example. If you set it in AD, it won’t sync that attribute until you edit the export in the ad sync tool.
I ended up getting it all to work just as intended fairly quickly being there was zero documentation that I could find regarding this part of it.
