Publisher Access

John E Garcia 0

I've been using Publisher for invoicing customers since 2009, created 1000's of invoices and I need access to these files for my business. What can I do now, I missed the deadline to convert these files to have access to them.

Answer 2

Hello John E Garcia,

Please refer to the AI-generated answer in this thread, as it provides a helpful overview of the available options.

Could you please confirm which version of Microsoft Publisher you previously used?

Publisher included with a Microsoft 365 subscription
A one-time-purchase version, such as Publisher 2021 or Office Professional 2021

This distinction is important because Microsoft 365 subscribers can no longer access Publisher after its retirement, while an existing, legitimately licensed perpetual installation may still allow the .pub files to be opened and converted, although the product is no longer supported.

If your business has an IT administrator, please ask the administrator to check whether the organization still has an older computer with Publisher installed and able to open the files. It would also be helpful to check for previously exported PDF copies of the invoices and backups stored on the computer, OneDrive, SharePoint, network storage, or another backup system.

If a working and properly licensed Publisher installation is found, please back up the original .pub files first, then use that installation to export the invoices to PDF as soon as possible.

If Publisher was available only through Microsoft 365 and no licensed perpetual installation remains, Microsoft does not currently provide another Microsoft application that can open .pub files directly.

Kind regards,

Answer 3

If you own a perpetual (one-time-purchase) version of Publisher, install or use that licensed copy to open the .pub files and bulk-export them; Publisher supplied through Microsoft 365 is no longer available after October 2026.

Your files have not been deleted by Publisher’s retirement. The available path depends on which Publisher licence you have. ^1^

If you own a perpetual Publisher licence

Perpetual versions can still be installed and used after support ends, although they no longer receive official support. This differs from Publisher provided through a Microsoft 365 subscription, which can no longer open or edit Publisher files after retirement. ^1^

Locate the Microsoft account, product key, installation media, or existing computer associated with your one-time-purchase copy.
Install or open that licensed Publisher version.
Copy the original .pub files to a separate backup before conversion.
Open several invoices from different years to verify that fonts, images, and layouts render correctly.
Convert them to:
- PDF for permanent viewing and printing.
- Word if future editing is required; complex layouts may change during conversion.

For a single file, select File > Export > Create PDF/XPS Document > Create PDF/XPS, select PDF, choose the appropriate quality, and select Publish. ^2^

Bulk-convert thousands of invoices

Microsoft supplies a sample PowerShell script for bulk PDF export. It requires a working, licensed installation of Publisher, so having the .pub files alone is not sufficient. Download Microsoft’s Convert-PubFileToPDF.ps1 sample from the retirement guidance, test it on copies of a few files, and then run it against the invoice folder. ^1^

# Open PowerShell in the folder containing the downloaded script.
# Convert every .pub file under the invoice directory.
.\Convert-PubFileToPDF.ps1 `
  -Filter "C:\Business\Invoices\*.pub" `
  -Recurse

The script reports successful and failed conversions and continues after errors. If an output file with the same name already exists, rename or move that output before rerunning the conversion.

Retain three sets during migration:

Untouched original .pub files.
Converted PDFs.
A conversion log or list of failed files.

If Publisher came only from Microsoft 365

A Microsoft 365 subscription no longer provides Publisher installation or access after the October 2026 retirement. The official guidance does not provide another Microsoft 365 application that directly opens .pub files. ^1^

The remaining documented options are:

Use a legitimately licensed perpetual Publisher installation, if your business already owns one.
Use a third-party .pub conversion service or application. Microsoft does not support these tools, and their accuracy varies. Because invoices contain business and customer information, prefer an offline converter and test it on non-sensitive copies first.
Ask a document-conversion provider with licensed Publisher to perform a controlled bulk conversion.

After producing PDFs, Word can open a PDF through File > Open, but the result is optimized for text editing and may not preserve the original invoice layout. For new invoices, Microsoft recommends Word rather than Publisher. ^1^
