Access Custom OneDrive in harmon.ie

Issue:

With harmon.ie, you cannot access personal OneDrives that are configured with a custom host.

Cause:

Your M365 administrator configured OneDrive with a different host than the other SharePoint sites. For example, the SharePoint site host is domain.com, and the OneDrive host is mysite.domain.com. harmon.ie cannot detect the OneDrive host setting and uses the standard SharePoint host URL.

Resolution:

Specify a mapping between SharePoint host URLs and OneDrive host URLs.

This is done using the provisioning registry key MySiteHostMapping. [Download reg key sample]
