The estos EWS Calendar Replicator read the needed information from the users' free-busy data (or "Availablitydata") on the Exchange Server.
The amount of data available depends on whether the estos EWS Calendar Replicator has permissions to be able to read the user's calendar data. If no permission is granted, only start and end times of appointemnts can be read. Does the service have full access to the user's calendar information, additional information is available like subject and private/public flag.
Connection data
To be able to communicate with the Exchange Server, the following connection information must be configured:
Hostname
The hostname of the computer on which the Exchange Server service runs.
If the host name has not been provided, the service will attempt to find the Exchange server using Autodiscovery.
For this to work, the autodiscovery service must be running for the Exchange Client Access Server.
Exchange API Version
For best possible communication, the version of Exchange API should be provided to the service. At this time, Exchange Server 2007 SP1, Exchange Server 2010, Exchange Server SP1, Exchange Server 2010 SP2 and Exchange Server 2013 can be distinguished using this information. Setting the version precisely to the version of Exchange Server in use is recommended. Newer versions of Exchange Server should use Exchange Server 2013. Exchange Server Version prior to 2007 SP1 will not be supported.
Using SSL
The SSL feature should be activated for secure data transmission. This is the default behavior for Exchange Server 2010.
In order to connect with SSL enabled, the computer running estos EWS Calendar Replicator must trust the Exchange Server certificate.
SSL is mandatory when using the Autodiscovery service.
User
The name for a user account, which has access rights to the calendar data for other users.
It is important that the user name is specified in Fully Qualified Domain Name (FQDN) format! Example: admin.user@domain.com
User account's password
The password for the user, which will be used for logging onto the service on the Exchange server.
The access to the Exchange Server via the Web interface of the Exchange server (short: EWS).
So that they can be used, the Admin must activate them in Exchange Server.
The user's availability data will be read. Other information will not be requested, nor will data written to Exchange Server.
The user account must be authorized to access the calendar data. For this purpose, the following procedure is recommended:
Released by user
The release by users is the way that is recommended. All users are informed that their data is used in the system and they have influence on this setting from the beginning.
Users who are considered for appointment replication can receive an e-mail asking to release their calender in the usual way in Outlook® for the replication account.
It is more convenient to send out an authorization request via Outlook® when the calendar service account is first registered at Outlook®.
All Outlook® versions differ with regard to their interface/menu configuration, therefore it is necessary to refer to the original documentation.
Its also possible to do this administratively via the Exchange Management Console
The release can also be done administratively, but it is strongly recommended informing the concerned users about the change beforehand.
The administrator requires one of the following applications for the release of the calendar, depending on which Exchange version is used.
The operation of the various programs differs so fundamentally that it is necessary to refer to the original documentation.
