ISC Networking and Telecommunications Email Services

• Zimbra Collaboration Suite
• Microsoft Exchange 2010

Select Zimbra if your organization:

• supports a mix of PC, Mac or Linux clients for mail.
• does not depend on third-party client access to a calendar system. The Zimbra web client has full-featured calendar support. There is limited support for other third-party clients at this time and separate credentials are required for calendar access.
• depends on ISC's recommended authentication platform, Kerberos.
• is a school that wishes to allow students to self-provision accounts.
• wishes to suport only a full-featured web client that works in any modern browser, or the same cross-platform client.
• considers cost a strong factor in your decision making.

Select Exchange if your organization:

• supports a majority of PC clients. Microsoft Entourage provides access to Exchange services for Mac users, but there are substantial feature gaps between Entourage and Outlook.
• does not depend on ISC's recommended authentication platform, Kerberos.
• has webmail users who primarily use the Internet Explorer browser. Other browsers offer less functionality with Outlook Web Access.
• does not consider cost a strong factor in your decision making.

Select both services if your organization:

• has a mix of business users, faculty, and students, and you support different classes of service for those constituencies.
• does not require full-featured scheduling across platforms and across services.
