This information is provided in the Zimbra Wiki for convenience. Support for operating systems and browsers is constrained by the Lifecycle Policies of third-party vendors; those products will be supported by a Zimbra release while their mainstream support phase overlaps with the Zimbra release. Products in their extended support period will receive best-effort support from Zimbra; you are strongly encouraged to use the latest versions of operating systems and browsers to ensure access to security updates.

Refer to the "System Requirements" in the latest revision of the documentation for your supported Zimbra release to keep up-to-date.
