Topic T1129 Applies to All NEO products


The problem applies to all versions of Outlook. Outlook reports 'Error in registry for "Exchange Extensions"' as below:

This may occur for a number of reasons but the net result is that Outlook has not shut down normally. The most common cause is a power failure. On the subsequent startup, Outlook reports this error in the Exchange Extensions.

  1. Often Outlook will self-repair this registry problem with the Exchange Extensions during the first startup after its appearance.

  2. If Outlook does not self-repair this, refer to Knowledge Base article T1141 - Repairing Outlook Environment Problems
