Case in point:

Microsoft 365: Change Meeting Organizer via PowerShell Cmdlet in Exchange Online

Allows the administrator of an Exchange Online tenant to change the organizer of an existing meeting or meeting series via a PowerShell cmdlet. This can be used, for example, to maintain continuity and history of a long-running meeting series in cases where the meeting organizer has a new role, is on leave, or during the offboarding process. Once the meeting is transferred, the new organizer will be able to maintain all properties of the event including meeting time and recurrence, attendees, and description. Meeting attendees within the Exchange Online tenant will not need to re-RSVP and the existing event on their calendar will be silently updated with the new meeting organizer information.A subsequent feature will enable users to to change the organizer via Modern Calendar in OWA, New Outlook, and Teams. For user-initiated transfers the new organizer must accept the meeting before the transfer completes.

GA date: May CY2026

How many meeting series have had to be erased and recreated when someone on your team left the organization? IYKYK. 😏

Copilot News:

Here’s a resource you may want to keep handy:

Deploying Microsoft 365 Copilot in five chapters

This is true, it’ll find stuff you didn’t know you had access to:

Copilot Won’t Fix Your M365—It Will Expose It: 8 Pre-Go-Live Repairs for IT Leaders

File both of these under “But how well do they work” for now:

• Create Agents in One-Click from your OneDrive

• Introducing M365 Copilot Agents in Office Apps

I like the idea of blocking individual SharePoint sites from Copilot. I haven’t been able to get it to work yet, but I’m troubleshooting. Has anyone else had a similar issue where you change the setting, but Copilot and Search still locate the documents anyway?

Non-Copilot News:

There were a number of educational articles about both existing and new features, especially in Purview, that I have seen over the last few weeks:

• Ediscovery for Teams Chat: The Complete Guide

• Deploying Purview Data Loss Prevention for Microsoft 365

• Protect your Sensitive Information in Remote Desktop Sessions

• Purview Auto-apply Retention Labels and SharePoint Autofill

• General Availability of Microsoft Purview eDiscovery Graph API for E3 Customers

This is a very interesting idea - a snapshot of your tenant configuration that you could rollback to?

Automating Governance: The New Standard for Microsoft 365 Tenant Snapshots and Remediation

This is also interesting. Viva Engage is one of those tools I occasionally look at with interest because its functionality isn't exactly the same as Teams', but it’s similar enough that I'm fairly certain I won’t be able to get users to use both. But what happens when communities can show up in Teams in the same Chat tab?
