Welcome to What's New in Microsoft 365

What’s New in Microsoft 365 is the successor to What’s New in Office 365. If you subscribed to the old list, you are still in the right place. The digest works the same way; only the name and the software behind it have changed.

Why a rewrite?

The original software had served well for years, but it was showing its age. Microsoft rebranded Office 365 to Microsoft 365 long ago, and the old codebase was increasingly hard to maintain and extend. Rather than patch around the edges, I rebuilt the service from scratch.

Better coverage

The new system should capture more of what Microsoft publishes. Most sources still come from RSS feeds, chiefly Microsoft Tech Community boards. Several important Microsoft blogs, however, never offered a reliable feed. The new software can scrape those sites directly when RSS is missing or is unreliable. Examples include the Microsoft 365 Blog, Microsoft Copilot Blog, Microsoft Security Blog, and several Power Platform blogs. Posts that the old tool would have missed should now show up in your digest.

You can see the full, current catalog on Sources.

What stayed the same

I tried to make the transition as seamless as possible. The digest still goes out Tuesday and Friday mornings. Messages still come from o365@lists.cannell.org. Existing subscribers did not need to re-subscribe, and past issues remain browsable in the archive.

One thing to check

Because the message subject line and branding now say Microsoft 365 instead of Office 365, your mail client may treat the digest differently. If you use rules, filters, or a safelist keyed on the old name, you may need to update them. If a digest goes missing, check your spam or junk folder first.
