Do I need any special Zimbra licensing to use the Blackberry sync service?
Yes. You must have Zimbra Mobile, also known as ActiveSync at 01.com, enabled for each mailbox with which you’d like to sync a Blackberry in the 01.com Zimbra cloud hosting environment. Zimbra Mobile is provided free-of-additional-charge with Business hosting purchased at an annual term, for an additional $1/month for Personal Hosting, and for a variable extra charge for Business hosting purchased at a month-to-month term, based on volume. Please see the business hosting calculator.
