When a Teams Retention Policy Goes Bad and Data Disappears

A change made to an Office 365 retention policy for Teams personal chats in the KPMG tenant removed data for 145,000 users. That’s unfortunate, and it underlines the need for admins to understand how retention policies work. Maybe the people involve did and it was a simple slip that could happen to anyone, but perhaps it will cause tenant admins to reflect on how they make changes to organization configurations.

Blocking Email Forwarding from Power Automate

Power Automate (Flow) can forward email from Exchange Online mailboxes to external recipients. This isn’t a great idea if you want email kept within the control of your data governance framework. Power Automate now inserts x-headers in the email it sends, which allows the use of transport (mail flow) rules to detect and reject these messages if required.

Teams Messages from Hybrid Users Scanned by Communication Compliance Policies

Communications compliance policies scan user messages to detect violations of company or regulatory rules. A change introduces support for hybrid users whose mailboxes are on Exchange on-premises servers. The change might not pick up many new violations, but it does increase the coverage and stops some violations sneaking through, which is always a good thing.

Capturing “Crucial” Office 365 Audit Events Requires E5 Licenses

Microsoft has released information about high-value Office 365 audit events and audit event retention policies. Both are part of a Microsoft 365 Advanced Audit offering. The MailItemsAccessed event is the first high-value audit event (we can expect more) and the retention policies are used to purge unneeded events from the Office 365 audit log.

Applying Holds to Teams Private Channel Messages

The Office 365 compliance framework can now to place holds on Teams compliance records created for conversations in private channels. You simply have to place holds on the mailboxes of members of the private channels and hope that no one removes the members from the tenant. If they do, the hold lapses, which seems like a pity.

Microsoft 365 Compliance and Security Centers Rolling Out to Office 365 Tenants

The Microsoft 365 Compliance and Security centers are roling out to Office 365 tenants where they’ll replace the old Security and Compliance Center over time. The new centers look fresher than the SCC, but looks can deceive and it’s much more important that the functionality exposed in the new portals work reliably all the time.

Microsoft Tries to Deprecate Classic Azure Information Protection Client

Microsoft retracted the announcement of the deprecation of the classic Azure Information Protection client and label management in the Azure portal. Office 365 sensitivity labels have taken over from AIP clients in most tenants, so the impact of this change is limited. However, if you still need to use an AIP client, you should move to the unified version.

Microsoft Removing Legacy Office 365 eDiscovery Tools

Microsoft announced the retirement of legacy eDiscovery tools from Office 365. The Exchange Online in-place holds and eDiscovery tool, Office 365 Advanced eDiscovery 1, and the Search-Mailbox cmdlet are being retired. All will be gone by mid-2020. It’s a pity to see the Search-Mailbox cmdlet being removed, but time and progress make this kind of thing inevitable.

OWA Supports Automatic Labeling for Office 365 Sensitivity Labels

OWA now supports the automatic labeling of outbound messages with Office 365 Sensitivity Labels. The new feature uses Office 365 sensitive data types to detect content in messages that should be protected, and once detected, the message is stamped with a label before it passes through the Exchange Online transport service.
