☁️What’s on my mind
The only thing worse than a bad PowerPoint is a Copilot-made one. I tried creating PowerPoint presentations with Copilot. Couldn’t do it.
My way of building slides is to create presentations while I think. Copilot, on the other hand, tries to create without thinking.
But here’s the thing: I still want Copilot’s help. I just don’t want to adapt my creative flow to its version of order and logic.
So I flipped the process.
I build my presentation the same way I always have. My slides, my flow, my typos (don’t care about them anymore).
When my draft is done, I call in Copilot and point it to the presentation. Let’s say my deck is about Microsoft Intune.
My first prompt usually goes like this:
“This is my 15-minute presentation about Intune. I’m missing 2–3 intro slides that explain what Intune is in simple terms.
I have 3 tasks for you:
1️⃣ Suggest content for those slides.
2️⃣ Fact-check the entire presentation.
3️⃣ Suggest improvements to make it clearer.”
A few seconds later, I have a pretty damn good analysis of my draft and a solid ground to make it better. 30 minutes later, I’m done.
Then it’s time for a second run with this prompt:
“I implemented your suggestions. Please fact-check again and review the slide flow and structure. Suggest where I should change the order, and explain why.”
The result? Each iteration gets sharper.
On the third run, I ask Copilot to: Double-check narrative flow, ignore areas I didn’t want to change from earlier feedback, and suggest final improvements.
At that point, the presentation is usually in great shape.
Takeaway:
Don’t build with Copilot.
Improve with it.
Copilot is:
🎯 a damn good co-editor,
🎯 jack sh*t creator.

Planner’s Newly Redesigned Interface. Microsoft Planner is getting a fresh look with enhanced navigation, responsive layouts, and a dedicated goals view for better task prioritization.
When the Enter Key Became a Liability in Microsoft Teams. Microsoft Teams lets you control what happens when you press Enter while writing a message. You can stick with Enter to send messages or switch to make it create new lines instead.
How to create multiple Mail Profiles in New Outlook. The New Outlook supports multiple mail profiles but lacks a user-friendly interface for managing them. Fortunately, you can do it in PowerShell.
☁️Copilot & AI
Making Copilot Chat Work for You. Microsoft 365 Copilot Chat shines when treated as a collaborative tool, not just a Q&A engine. It organizes messy information, clarifies trade-offs, and translates technical details into stakeholder-friendly drafts. However, it doesn’t “know” your tenant, so vague prompts or unverified outputs can amplify risks. Use it deliberately to accelerate thinking and communication, while ensuring accountability and tenant-specific accuracy.
New M365 Copilot Researcher output formats. Microsoft 365 Copilot’s Researcher agent is expanding its export options. New formats include PowerPoint, PDF, Infographic, and Audio overview, alongside updates to Word and Pages export experiences. These changes aim to enhance flexibility for users and are expected in late April 2026.
Copilot Studio agent security: Top 10 risks you can detect and prevent. AI agents come with risks like misconfigurations, excessive access, weak authentication, overly broad sharing, unauthenticated access, unsafe HTTP requests, and dormant agents. Microsoft Defender and Copilot Studio offer tools to detect and mitigate these gaps.

Find and Unpublish Internet Calendars in Microsoft 365. Published internet calendars in Microsoft 365 pose security risks like exposing sensitive events and organizational patterns.

Bridging the Gap: Mastering M365 Cross-Tenant Calendar Sharing, Exchange Online Organization Relationships let you share calendar availability across Microsoft 365 tenants. Ideal for mergers, holding structures, or joint ventures, it enables seamless scheduling while keeping data separate.
☁️Security & Data Governance
What to Do When SharePoint Storage Is Full. SharePoint Online storage issues often stem from unnoticed “storage creep.” Version histories, inactive sites, retention policies, and recycle bins quietly consume space. To fix this, audit storage usage, archive inactive content, trim version histories, clear recycle bins, or purchase more storage if needed.
Why ‘Never persistent’ isn’t really never persistent: understanding browser sessions in Microsoft 365 Web Apps. Conditional Access policies with non-persistent browser sessions depend on web app architecture and browser settings. Teams maintains session state using token storage and silent renewal, making it less reliant on cookies. Outlook and OneDrive rely heavily on cookies, making them more sensitive to session restoration settings like “Open tabs from the previous session.”
☁️Noteworthy (long)reads
When Everyone Is an Expert. Titles in tech often inflate faster than the skills they represent. From “desktop publishing” to “cloud expert” and now “AI strategist,” buzzwords evolve, but true expertise remains rooted in experience and understanding. Labels can mislead, especially with AI’s ability to generate convincing profiles. Focus less on titles and more on the substance of someone’s work and the depth of their knowledge.
