What Happens to Your .pub Files After Microsoft Removes Publisher from Microsoft 365 on October 13, 2026

On October 13, 2026, Microsoft will remove Publisher from all Microsoft 365 subscription plans. After that date, you won’t be able to open .pub files using Publisher within Microsoft 365. If you depend on Publisher and .pub files, this change means you need to plan how to access and manage those files going forward.

Why is Microsoft removing Publisher from Microsoft 365 and what does that mean for users?

Microsoft is removing Publisher from Microsoft 365 as part of a shift in their product focus toward applications with wider usage and more modern features. Publisher serves a smaller user base compared to core Office apps like Word, Excel, and PowerPoint. For users, this means Publisher will no longer be included or supported in any Microsoft 365 subscription after October 13, 2026. You won’t be able to install or update Publisher through Microsoft 365 anymore. Existing installations linked to Microsoft 365 may lose support or functionality over time. If you want to keep using Publisher, you will need to use a standalone version outside of Microsoft 365 or switch to alternative software.

Why won’t .pub files open in Publisher after October 13, 2026?

.pub files require the Publisher application to open and edit because they use a proprietary format unsupported by other Microsoft 365 apps. Once Publisher is removed from Microsoft 365, no subscription plan will include the application needed to open .pub files. This isn’t just a change to the user interface; it means the software and its licensing will no longer be available within Microsoft 365. Microsoft may also disable any cloud services linked to Publisher, making it impossible to access .pub files through the subscription. Without Publisher, .pub files can’t be opened or edited within Microsoft 365.

What are the consequences for people who use Publisher and .pub files regularly?

If you rely on Publisher, you won’t be able to open, edit, or create .pub files in Microsoft 365 after October 13, 2026. Projects saved as .pub files will need to be exported to other formats before the deadline or transitioned to different software. Sharing .pub files with colleagues who use Microsoft 365 will become difficult since they won’t have Publisher to open those files. For archived .pub files, you must either keep access to a standalone version of Publisher or convert those files into formats compatible with other applications. Without these steps, you risk losing access to important documents or having to recreate content from scratch.

What are the best alternatives to open and edit .pub files once Publisher is no longer available?

You have several options to open or convert .pub files without Publisher in Microsoft 365. For example, LibreOffice Draw can open .pub files, though complex layouts might not convert accurately. Online conversion services can change .pub files to PDF, Word, or other formats, but they may have file size limits and privacy concerns. Adobe InDesign does not support .pub files directly but can import PDFs if you convert Publisher files beforehand. Many users export .pub files as PDFs before the deadline to preserve formatting for viewing and sharing, though editing will be limited. Each alternative involves trade-offs in accuracy, cost, and ease of use. It’s a good idea to test your typical documents with these tools before fully relying on them.

How can you prepare your Publisher files and workflow before October 13, 2026?

Start preparing well before October 2026 to avoid disruption. First, back up all your existing .pub files in a safe location. Then, export or convert important files to widely supported formats like PDF or Word using Publisher’s Save As or Export features. For example, you can save a .pub file as a PDF for sharing or archiving. If you want to keep editing desktop publishing files, research and try alternative software to find one that meets your needs. Update your workflow accordingly and inform your team or clients about this change so everyone knows how to handle Publisher files going forward. Planning ahead will help you avoid last-minute problems when Publisher is removed from Microsoft 365.

Conclusion

Since Publisher will no longer be part of Microsoft 365 after October 13, 2026, it’s important to act now. Back up your .pub files, convert important documents to other formats, and explore alternative software options. Taking these steps early will ensure you don’t lose access to your files and that your publishing work continues without interruption after Publisher’s removal.
