After a login request, an XML document should be displayed. The Exchange Web Services should be activated then.

- Domain user account with reading rights on Active Directory® and Exchange must exist.
In order to read the neccessary data from the listed services, a user account must exist which has read access on the following data:
The authorizations for the free-busy data normally depend on the permissions of the individual users (regarding this, see the Exchange Server Connection section).
