Final Steps—Initial Sync

The first time users open Outlook after ZCO is installed, their Outlook mailbox must synchronize with the Zimbra server. If users have been using the Zimbra Web Client and have email messages, chat archives, folders, tags, contacts, personal distribution lists, personal calendars, appointment reminders, and/or tasks on the Zimbra server, this information is synchronized with their Zimbra profile in Outlook. The initial synchronization can last a few minutes or longer, depending on the size of the mailbox being synchronized.

Note: Users can configure their ZCO download settings to download only email message headers when they sync with the ZCS server. When only headers are synced, the initial sync is faster. Users mark messages that they want to download and the messages are downloaded on the next sync.

If users create the default Zimbra profile, their synchronized data is saved in the zimbra.zdb file located in the user’s Local Settings\Application Data\Microsoft\Outlook folder.

If users used Notes and Journal in Outlook, these items will be lost when an initial sync is performed. In order to keep their Notes and Journal entries, users should save these Outlook items in .pst format before syncing and then import the .pst file after the initial sync is performed.

Note: If you are running McAfee® Security On-Delivery E-mail Scanner feature, the initial sync is very slow. We recommend that this option be turned off for the initial sync with the Zimbra server.

Users can click Tools>Send/Receive>Send/Receive All (shortcut key F9) to update Outlook and the Zimbra server with changes made since the last sync.

Important: When the Zimbra server is restored from a Zimbra backup session, users must perform an initial sync with the Outlook client when they log on.
