M365 Archive

About this archive

I'm Merill Fernando. I build tools and write about Microsoft 365 and Microsoft Entra to help admins keep up with constant change.

Why I built this

Message Center posts are useful, but they are hard to link to, search, and reference outside the Microsoft 365 admin center. I built this archive so posts can be found quickly and shared from places like Entra.News.

This site is for reference only. Message Center posts are customized by tenant, so always use your own tenant's Message Center as the source of truth.

How it works

A scheduled job reads Message Center posts from a Microsoft 365 test tenant through Microsoft Graph, saves each post for history, and publishes a searchable static site.

The site also imports Microsoft 365 Roadmap RSS items, generates static pages, and exposes sitemap, RSS, and AI-friendly index files for discovery.

Help improve tenant coverage

Some entries may be missing, especially posts shown only to EDU, government, or tenants with additional products and licenses. I'm always eager to connect with folks who can help make the archive more complete.

If you have a test tenant and can create a read-only service principal for Message Center access, please reach out through LinkedIn, X, or Bluesky.
