If you’re interested in deploying backups for SharePoint Online, you might be doing so to prevent data loss through accidental user deletion. However, Office 365 retention labels and policies can help prevent accidental deletion too. And the best thing is that retention policies and labels are part of Office 365 E3, so you don’t have to pay more to get protection.
Microsoft released an update for the unified labeling version of the Azure Information Protection client needed for Office 365 sensitivity labels, which now boast auto-label support. Solid progress is being made to move sensitivity labels to the point where they are considered to be generally available, probably later this year. In the meantime, pay attention to the premium features like auto-label which require more expensive licenses.
Microsoft announced that the Office 365 E3 and E5 plans will receive new Information Protection licenses. They’re preparing for the introduction of sensitivity labels and the increased use of encryption to protect access to content in Office 365 apps like SharePoint Online, Exchange Online, OneDrive for Business, and Teams. You don’t have to do anything to prepare for the new licenses, but it’s nice to know what they are and how the licenses are used.
Rights management and encryption are likely to be a much more common Office 365 feature in the future. Sensitivity labels makes protection easy for users to apply through Office apps. The downside is that protection makes content harder to access for some Office 365 and ISV functionality.
A question asks how to remove a bunch of emails from a shared mailbox. You can use OWA to do the job, especially with its Cleanup Mailbox option, but perhaps some administrative action is needed.
