Microsoft Surface Hub 2 SmCamera - Manual (Page 43)

Mail, calendar, Microsoft Teams, and related resources depend on a compatible device
account. For Teams or Skype for Business to work, the device account must have a valid
SIP address. The device will try to find the SIP automatically. If an SIP address can't be
found, the UPN will be used as the SIP address. If this isn't the SIP address for the
account, you'll need to provide the SIP address.
The Exchange server address will need to be provided if the device can't find a server
associated with the sign-in credentials. Microsoft Surface Hub will use the Exchange
server to talk to ActiveSync, which enables several key features on the device.
