Working with Microsoft Exchange


Q: What does Groupcal do?

A: Groupcal allows you to use your Exchange-based calendar capabilities via iCal. You can share or view calendars with co-workers who use Outlook and Microsoft Exchange and manage your Exchange-based calendars and schedules from within iCal. Groupcal can cost-effectively enhance productivity, integration and reduce support costs for employees using Apple's OS X.

Groupcal + OS X's Mail application = Exchange-based calendaringthe iCal way!

A: Groupcal is available for purchase via Snerdware's Kagi e-store sales page (includes information for volume pricing and site licenses). Snerdware also offers educational, government, and non-profit organizational discounts to qualifying parties. For more information please contact us.

Q: Where can I get support for Groupcal?

A: Snerdware products come with 1 year of no-charge email-based support.  In addition, we maintain a collection of Knowledgebase articles.  We do not guarantee a support response time. Enterprise customers wanting to purchase maintenance contracts should contact us.

Q: Do I need to be at work to use Groupcal?

A: If you can reach your mailbox with Outlook Web Access you can use Groupcal from that location. Thus, if you can access Outlook Web Access via the Internet, you can also use Groupcal from anywhere you have an Internet connection.


Q: Do I need a Microsoft Exchange Server 2000 or 2003 account to use Groupcal?

A: Yes.

Q: What versions of Microsoft Exchange are compatible with Groupcal?

A: Currently, Microsoft Exchange 2000 Server with Service Pack 3 (or greater) and Microsoft Exchange Server 2003 are supported. We anticipate that Exchange Server 2007 will also be supported by January 2007 or sooner.

Q: Do I need to install anything from Snerdware on my Exchange Server?

A: No.

Q: What Exchange Server configuration options will I need?

A: WebDAV (Outlook Web Access) must be enabled on the Exchange server.

Q: With which Exchange-server authentication schemes is Groupcal compatible?

A: Groupcal can access Exchange using Windows Integrated (NTLM), Negotiate, Digest, Basic, Kerberos, or MIT Kerberos Authentication. AddressX also supports Forms-Based Authentication for Exchange 2003.

Q: Will Groupcal work with Microsoft Exchange 5.5?

A: No. Groupcal is designed to work with Microsoft Exchange 2000 or 2003. Exchange 5.5 does not contain the WebDAV support necessary for Groupcal to function.

Q: Are versions of Groupcal available for operating systems other than Apple OS X?

A: No. Groupcal 3 is only available for OS X 10.4.

Q: Will Groupcal support Microsoft Entourage or Communigate Pro?

A: We have no plans to support Entourage. Groupcal 3 is designed to work with iCal on OS X 10.4 via OS X's Sync Services.

Q: Will Groupcal support Exchange clones or Google Calendar?

A: We're considering support for Kerio Server and some integration with Google Calendar, but currently there's no schedule for such work. If you have an enterprise-level requirement, please contact us.
