The log file containing the above error is the most recent file located at %LOCALAPPDATA%\Colligo\Engage\OutlookLogs.

Cause: Microsoft Office Update KB4011162 introduced a change to disable the feature to set the Default Home Page of a PST folder. As a result, Colligo Email Manager is prevented from loading properly.

1. Navigate to Control Panel > Add/Remove Programs or Control Panel > Programs > Programs and Features.
2. Navigate to View installed updates.
3. Search for KB4011162.

Workaround: Download the attached zipped package, close Outlook, and import the applicable .reg file to add an override to re-enable this functionality. Alternatively, update the registry as described below.
