Important:

  • All installations of Microsoft Outlook and Microsoft Office must have the latest updates from Microsoft.

  • Make sure Outlook is closed before installing ZCO.

  • Make sure your Antivirus software is disabled during the initial sync.

  • If you are setting up multiple Outlook clients, consider staggering the client setups so that they don't all sync at once and saturate your Internet connectivity.

Creating an Outlook Profile for ZCO

If there are no existing Zimbra profile the fist time you open Outlook after installing the ZCO, you will be prompted for the information to create one.

Zimbra Server Configuration Settings

  • Server name: your mail server hostname (zmail.his.com or zmail2.his.com).
  • Use Secure Connection: Check.
  • Email address: your full email address, e.g. sample@yourdomain.com
  • Password: As provided
  • Click OK

Once configured, Outlook with ZCO will start to sync any emails, contacts and calendar items it finds on the Zimbra server.

Note: the first Sync can take a while if you have a big mailbox (5 GB or over) so be patient.
You can always access your email via webmail: https://zmail.his.com in the meantime.

To make your initial synchronization faster, you can do the following:

  • If you previously accessed your Zimbra account using an IMAP account type or the webmail client, you may want to empty the Junk, Trash and Deleted/Deleted Items folders and delete or archive any older mail items. Accounts with larger mail folders take longer to sync.

  • If the sync fails to start automatically, press F9 to manually start the synchronization.

Important:

When you initially install and run the ZCO, a new Outlook profile named Zimbra will automatically be created. This means that your previous account data (emails, contacts and calendar events) will be on a different Outlook profile.

The data would need to be migrated from the old profile to the new profile via import/export within Outlook.
