The following are known limitations. This section will be updated as issues are addressed or updated.
Currently, Cloud Backup does not support the back up and restore of Groups created via Yammer. They will not appear in the list of Groups available for back up. This is an item for support on the Cloud Backup road-map.
Deletion & Re-Association of a Group
There is limited support of deletion & re-association of a Group. This is only supported when the display name of the new Group and the alias (email address) match the original Group display name and alias.
Discovery of Groups that are not fully provisioned
Office 365 defers provisioning Notebooks and Files for Groups until a user has interacted with that component. Cloud Backup will not back up that portion of the Group until provisioning occurs and is detected.
