Challenge

On a host with both Veeam Backup for Microsoft Office 365 and Veeam Backup & Replication installed, SharePoint restore initiated from Veeam Backup & Replication fails with “Object reference not set to an instance of an object” error.

Cause

This error occurs if the content type of a restored item has an empty Name attribute.
