Collaboration Services

Free/Busy & Global Address List Synchronization for Exchange

Are you in the midst of a company merger or acquisition? Do you have a “multi-forest/multi-org” Exchange environment? Collaboration Services™ provides real-time synchronization of free/busy information and Global Address Lists (GALs) between organizations. It delivers the level of protection that you require by maintaining secure boundaries between Exchange organizations and Active Directory forests while providing a transparent collaboration process. Whether you need time to plan your Exchange migration, or have communications and scheduling requirements with partners, Collaboration Services can improve your productivity.


Transparent to Users
Stop frustrated end users from calling your help desk and reduce e-mail traffic when you use Collaboration Services to display free/busy information between Exchange organizations. Your end users can now also display the calendar details of colleagues, all using your existing Outlook client.

No changes to the Active Directory or Exchange configuration are required.

Maintain Administrative Control
Allows you to decide which objects and attributes to publish and which collaboration partners will be allowed to subscribe to your collections, so you still maintain total control over your Exchange environment.

Preserve Security
Provide value-added services to your end users while sustaining your security objectives using compressed, encrypted messages over SMTP. There's no need to set up trusts, additional accounts or open extra ports. No security-related user data, such as security IDs (SIDs) or passwords is ever transmitted or stored anywhere.

Reduce Workload
Eliminate manual tasks of duplicating contacts in several address books with automatic updates. Maintain productivity company-wide by removing the need to send multiple e-mails to find available meeting times.

Flexible Data Format
Maintain your preferred data format with Collaboration Services’ Display Mappers, regardless of how the original collection displays data. Select the format you like and all subscribed-to collections will be automatically reformatted.
