According to a Microsoft presentation at TEC 2021, organizations moving to the cloud from on-premises infrastructures should pay attention to security weaknesses that could be introduced from on-premises accounts. It's all too easy to allow a highly-permissioned on-premises account to evolve into one that has full access across a Microsoft 365 infrastructure, and that can lead to terrible consequences if attackers penetrate the on-premises infrastructure and compromise the accounts.
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. That is, if you have the necessary Office 365 E5 licenses to use adaptive scopes...
Adaptive scopes are a new way to dynamically target sets of locations (sites, users, and groups) for Microsoft 365 retention policies. In this article, we discuss the basics of adaptive scopes and how to build the filters used in the scopes, and then how to use adaptive scopes in retention policies. Adaptive scopes are well suited to the kind of processing needed by large enterprises, which is good because they required Office 365 E5 licenses.
Microsoft has issued security updates for Exchange 2013, 2016, and 2019. The updates can only be applied to servers running up-to-date cumulative updates. Organizations running Exchange 2016 or 2019 should apply the updates as a matter of urgency because of a known vulnerability circulating in the wild.
Although it's easy to write scripts using cmdlets in the Microsoft Graph PowerShell, SDK you probably don't want to execute the scripts interactively. In this article, we explain how to use certificate-based (app-only) authentication to run scripts. This is very much an explanation about how to accomplish the task in a testing environment. If you want to run scripts in production, some extra work is needed.
Microsoft 365 Desired State Configuration (DSC), is a way to capture details of a tenant's configuration using PowerShell in such a way that any changes made to the configuration can be easily detected. DSC allows administrators to understand when configurations change so that they can take action when necessary. In this article, Sean McAvinue explains how to use DSC to capture and report details of your Microsoft 365 tenant.
The Office news at Microsoft's Fall Ignite event was dominated by Teams and technology associated with Teams. A new Microsoft 365 app called Loop will be available in 2022 and we'll have the chance to use Connect IQ to make our messages even more intelligent than they are now. And if you really get funky, you can join a Teams mesh meetings in a virtual environment. But the bad news is that Teams Shared Channels are delayed until preview in early 2022.
Microsoft has made end-to-end encryption available in preview for Teams 1:1 calls on Windows and Mac desktop clients. The full roll-out to tenants is due in November. End to end encryption means that the workstations involved in both sides of a conversation do extra work to secure the communications. Although E2EE results in extra protection, it means that some call features cannot be used.
I promised to share my schedule for Microsoft Ignite 2021, this week 2nd-4th November, so read on to find out my thoughts when I checked out the schedule, and which sessions I chose. And join Paul Robichaux and myself for the Practical 365 Podcast - Live from Ignite. We'll be covering the biggest announcements from the day with full commentary.
In many organizations, Microsoft 365 is a significant investment. However, you get so much with Microsoft 365 E3 licenses that many organizations are unaware of, including beneficial features across Productivity, Compliance, Security, and Device management. Kat Greenan shares some of her secrets and the hidden gems that can be found in a Microsoft 365 E3 license.
Microsoft Ignite 2021 happens (virtually) on Nov 2-4. There are tons of sessions scheduled and in this post we consider some important Microsoft 365 topics that we hope Microsoft will cover to help technologists plan tenant development over the coming year. Above all, we're looking forward to being able to attend conferences like Ignite in person so that we can learn from experts from inside and outside Microsoft.
