Exchange Online Introduces DANE and DNSSEC for Outbound Email

In a December 24 announcement, Microsoft says that the roll-out of DNSSEC and DANE support in Exchange Online will start in mid-January 2022. Because this is a big change for the Exchange Online infrastructure, Microsoft is using a phased deployment which won't complete until mid-May.

How to Use Cloud Shell from the Microsoft Teams Admin Center

Microsoft has updated the Teams PowerShell module to allow it to run in a Cloud Shell session. This is good news if you need to run one or two Teams cmdlets without access to your normal workstation, but it's not so good if you expect to run code which runs well in normal PowerShell sessions.

We checked out the functionality available in Teams Free and compared what you can get for nothing against what Microsoft says is available in Teams Essentials for $48/user/year. Small organizations certainly have a choice, and for an extra $12/year, they can get Teams and Microsoft 365.

Using Adaptive Scopes with Retention Policies for SharePoint Online Sites

Adaptive scopes are a new way to target locations for Microsoft 365 retention policies. Previously, we covered how to use scopes to find users and groups. Now, we move to describe how to use adaptive scopes to find SharePoint Online sites and OneDrive for Business accounts. The process is not quite as easy as it is to create scopes for users and groups, but once you understand how to add custom properties to sites, you're home free and easy.
