Your .pub files are not automatically deleted when Microsoft Publisher is discontinued. The key change is that Microsoft 365 subscribers will lose access to Publisher on October 1, 2026; support for perpetual Publisher versions ends October 13, 2026, but Microsoft says those versions can still be installed and used after support ends. Because access depends on the Publisher app, export important files before the relevant deadline if you need to view or edit them later.
What happens to existing Publisher files?
Publisher files and the Publisher application are separate. Microsoft’s discontinuation announcement concerns access to the app; it does not say that .pub files stored on your computer, OneDrive, or SharePoint will be deleted. But a file still needs compatible software to open, and Microsoft 365 subscribers will no longer be able to use Publisher after October 1, 2026.
Microsoft recommends converting important files before that date. A PDF gives you an exported version for viewing and printing. It is not the same as preserving an editable Publisher document.

Which deadline applies to your Publisher version?
| Publisher version | What changes | What Microsoft says afterward |
|---|---|---|
| Publisher included with a Microsoft 365 subscription | Access to Publisher ends October 1, 2026. | Subscribers will no longer be able to open or edit Publisher files in the app. |
| Perpetual Publisher version | Support ends October 13, 2026, the same date support ends for Office LTSC 2021 and Consumer Office 2021. | Microsoft says the app can still be installed and used beyond the end of support. Continued use does not mean continued support. |
These are different outcomes: losing subscription access and ending support do not mean that every Publisher installation stops working or that stored files are erased. See Microsoft Support’s Publisher retirement guidance for the stated dates and details.

How to find and preserve your .pub files
- Search your storage locations. Look for .pub files on your PC and in OneDrive and SharePoint. Check relevant folders and shared locations, not just the documents folder.
- Sort files by what you need to do with them. Mark which designs only need to remain viewable or printable and which ones you may need to edit.
- Export important files to PDF while Publisher is available. In Publisher, open the file and select File > Save as. Choose a location, select PDF as the file type, and save.
- Inspect the exports. Open representative PDFs and check their pages before relying on them as your preserved copies.
- Keep a separate backup of important originals and exports. A backup protects copies against loss; it does not convert a .pub file or make it editable in another application.
Can you still edit a Publisher file after exporting it?
A PDF preserves an exported appearance for viewing and printing, but it does not preserve the original Publisher editing experience. If you need to revise text, Microsoft describes converting a PDF to Word: open Word, select File > Open, choose the PDF, and confirm the conversion.
Word’s converted document is optimized for text editing, not guaranteed to match the Publisher layout. Microsoft warns that layout can vary, particularly for documents with many graphics. Try the conversion on representative files and inspect the result before depending on it for future revisions.
How to export many Publisher files
For a large collection, Microsoft provides a sample PowerShell script to guide individual or bulk PDF export. It requires Publisher to be installed and licensed. The example can process a file, the current folder, or a specified folder, with recursive processing available as an option. Microsoft recommends modifying and testing the sample for your intended use rather than assuming it fits every collection.
