5.3.3.1 Microsoft Exchange Server
If Exchange Server is used, additional requirements apply.
You must create a user in the Exchange Server who uses the same Windows user account ('swyxpbx') under which the Swyxservices also run. See 5.3 Preparation for Installation
After this action, SwyxServer can access the Exchange server via the MAPI interface and the appointment-based call management is available to Swyxusers.
