Synchronize contacts with MS Exchange

Cloud administration overview


I registered the Essence in JabloTool, selected Settings, Synchronization and wanted to synchronize the contacts in Essence with Microsoft Exchange. After confirming the login details to Exchange, JabloTool showed the error message:

Error - credentials are not correct

What to do?

Check these points:

    1. Is your Essence up-to-date? In JabloTool select Settings, Firmware update.
    2. Have you filled in the login to Exchange correctly? Ask your administrator.


User name and password are the same as when you login to your company Exchange account. JabloTool will identify the address of Exchange server based on your email address. This is done automatically as JabloTool uses the Autodiscover service.

If configuration completed by Autodiscover is not correct JabloTool will offer you advanced configuration.

Advanced configuration

Domain = Microsoft Active Directory domain
Server address = address of Exchange Web Services, e.g.

Ask your Exchange administrator about these settings.

Does your MS Exchange meet the requirements of JabloTool? Ask your administrator.
