Microsoft has confirmed that Publisher will be retired in October 2026. If your business still uses it for newsletters, flyers or templates, now is the time to plan your transition.

After the retirement date, Microsoft 365 subscribers will no longer be able to open or edit Publisher files.
This means any .pub files your organisation still relies on could become completely inaccessible.

Let’s break down what’s happening, and what you need to do.

What’s happening to Microsoft Publisher?

Microsoft has announced that:

  • Publisher will reach the end of life in October 2026
  • It will be removed from Microsoft 365
  • Users will no longer be able to open or edit .pub files after this date

Standalone perpetual versions (e.g., Office 2021) may still open Publisher, but they will no longer receive security updates and could become unreliable over time. 

Why is Microsoft retiring Publisher?

According to Microsoft, many of Publisher’s features now exist in:

  • Word (for layout and templates)
  • PowerPoint (for posters, flyers, and visual content)
  • Microsoft Designer (for AI‑assisted design)

Publisher is older, desktop‑based, and lacks cloud features like collaboration.
Microsoft is focusing on more modern tools instead.

What does this mean for your business?

If your organisation uses Publisher today, you could face:

Inaccessible files

From October 2026, Publisher files will not open in Microsoft 365 at all.
Your existing documents could effectively be “locked”.

Workflow disruption

If you rely on Publisher for:

  • Templates
  • Internal newsletters
  • Flyers
  • Labels or business cards

…you’ll need to rebuild these in another app.

Migration challenges

Converting .pub files can be fiddly, and layouts may not transfer perfectly.

What you should do now

Find all your .pub files

Check:

  • Shared drives
  • OneDrive
  • SharePoint
  • Individual PCs

Convert important files before the deadline

Microsoft recommends converting to another format before 1 October 2026.

The easiest options are:

  • PDF, for archiving or sharing
  • Word, if you need to keep editing the content

Consider automation for bulk conversion

Microsoft provides a PowerShell script that batch‑converts .pub files to PDF.
This is helpful if you have hundreds of files.

Choose your replacement tool

Most businesses replace Publisher with:

  • Word, for text‑heavy documents
  • PowerPoint, for visual layouts
  • Microsoft Designer, for quick branded content
  • Canva, easy and user‑friendly
  • Affinity Publisher, for more advanced desktop publishing

Don’t leave it too late

Many SMEs won’t feel the impact until they suddenly can’t open an important file.
By then, it may be too late to recover it easily.

The key steps are:

  • Review your files
  • Convert them now
  • Move your templates to a supported tool
