Is data at rest on SharePoint Online (Office 365) storage encrypted? I understand RMS would allow us to encrypt all SharePoint Online data, but we do not have a need for RMS technology at this time. Therefore, I'd like to know if all SharePoint Online data is encrypted (using BitLocker for example) while at rest without RMS. Seeing how SharePoint Online services are provided using multi-tenant storage, this is a concern for our business.
Thanks,
Paul
