(Applies to: Epicenter Server)

Problem: when an update is made to a contact in a source address book, such as the updating of a phone number, Outlook 2010 users do not see the update but Outlook 2007 users do. This problem is easy to identify because the "Notes" field in Outlook will contain a list of edit modifications. These notes are not generated by Epicenter.

Cause: Outlook Social Connector (OSC)

Solution:

Microsoft provides instructions for disabling this behavior in OSC. Please see:
http://support.microsoft.com/kb/2020103

More information about the behavior can be found here:
http://www.msoutlook.info/question/599

There are instructions on that page for disabling OSC, or search Google for Disable the Outlook Social Connector.

Once you've done that, you'll go to Epicenter, select Task / Strict Updates, then send an update to force all fields to update.
