Exchange Hybrid Configuration Wizard log file locations

The Hybrid Configuration Wizard (HCW) is an incredibly powerful tool. A single wizard both updates the hybrid configuration object as well as configures your on-premises Exchange environment, Exchange Online and Exchange Online Protection (EOP). The first part is usually not the problem, but the following phases of the process sometimes fail.

If you run into an error there’s usually a referral to the log file included but if you work more often with the HCW you may automatically navigate to the following path:

$exinstall\Logging\Update-HybridConfiguration

While this worked for the legacy HCW, the log for the new ‘cloud application’ HCW has a different location:

$ENV:appdata\Microsoft\Exchange Hybrid Configuration

The new HCW includes a link to the log files in the wizard, but if you need to consult the logs when you’re not actually working in the HCW it’s good to know the location.
