ISC Networking and Telecommunications Email Services

ISC Networking & Telecommunications offers two email services:

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.
Consult with ISC regarding your service selection if there are mitigating factors not listed here.

Zimbra Service Alerts

2:05pm, 10/18/2016 - We are seeing problems with one of the four Zimbra mailbox servers and are rebooting that server. Some users may see that clients, including the Zimbra Webmail Client, are slow or unresponsive. We anticipate that rebooting the server will address that problem. Updates as we can.

Update: 2:30pm, 10/18/2016 - The Zimbra service is now stable and we are investigating the root cause.

Update, 1:00pm - Microsoft is reporting that service has been restored. Please see the details of this incident.

Our own experience has shown intermittent problems with connectivity. Microsoft is working on the problem and we will send updates as we receive them.
