TL;DR: Microsoft Publisher will be removed from Microsoft 365 in October 2026. After that, no security updates, no support, and no new installations. Your existing .pub files will not be openable by any Microsoft tool. Use a free alternative like PubViewer or LibreOffice Draw to view them.
What Is Happening?
Microsoft officially announced that Microsoft Publisher will be retired in October 2026. This means:
- Publisher will be removed from all Microsoft 365 subscription plans
- No new installations will be possible after retirement
- Existing installations will continue to work but will receive no security updates or bug fixes
- Microsoft will not offer Publisher as a standalone product
- There will be no successor or replacement from Microsoft
⚠️ Why this matters: After October 2026, there will be no officially supported way to open .pub files from Microsoft. If you have archived Publisher documents — flyers, brochures, newsletters, business cards — they could become inaccessible unless you take action now.
