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.

Penn o365

3:30pm Upon further investigation we discovered that an operator configraution error was applied at 2:35pm that caused the "too many hops" error. This was fixed at 3:02pm. We apologize for this disruption in service and will be reviewing our processes to avoid a similar occurrence in the future.

7/7/2016, 3:00pm - We have received reports of users receiving non-delivery messages from PennO365. We are still trying to investigate the situation but it seems to happen when a PennO365 user tries to send to another PennO365 user. There does not seem to be a problem sending or receiving from other mail systems. We will send updates as we can.
