Hello Dana Gurnee
Thank you for sharing your experience with Publisher 2007, that’s actually very useful to know. Older Publisher versions use a different installation model
Which explains why they can still run side by side with Microsoft 365 in some cases, even though newer perpetual versions cannot. That insight may also help other users who are in a similar situation.
Regarding converting Publisher 2007 files to PDF, since that version doesn’t include built‑in PDF export, you should try looking for Microsoft Print to PDF function:
Open the file in Publisher 2007, Select File > Print. From the Printer list, choose Microsoft Print to PDF
If this function is available in Publisher 2007, it could be a practical way to convert file to pdf without converting to another program.
Because This creates a standard PDF that can be viewed, shared, or sent to a printer. It’s especially useful when direct PDF export or older add‑ons are no longer available.
