Yes.

"Help desk services" is unlimited, 24/7 access to our help desk, either for another help desk, or directly to Zimbra users, to help resolve client-side issues.

In fact, a number of the computer consultants who recommend our service do just that, as do organizations in addition to private companies, schools and state government agencies.

This means if you have your own Zimbra installation/server already, you can purchase just the end-user, tier-1, help desk support for the Zimbra product from 01.com. We charge either monthly based on the number of help desk personnel we will be supporting, or in the case of direct Tier-1 support, then monthly per user, with a minimum of $250/month, and activation fee of one-month's service. Please contact us for more information and a formal proposal/quote.
