401 Unauthorised on SharePoint Sites

If you see an error like the below on your CloudCover 365 backup job, it means that Veeam is unable to read the SharePoint site.

[Error] Failed to process site: (https://*-7b3ae07bad1261.sharepoint.com). The remote server returned an error: (401) Unauthorized
The highlighted string of characters indicate that the site was created by an application, which Veeam is unable to read.

The resolution for this would be to exclude the site from the backup as the site won’t contain any data that needs backing up.
