- Scenario
- Preparing for the discontinuation of Microsoft 365 Publisher and evaluating Publisher 2021 as a long-term replacement for handling existing files.
- Observed behavior
- Microsoft is discontinuing Publisher in Microsoft 365, raising concerns about future access, feature updates, and document compatibility for perpetual-license users.
Before transitioning away from Microsoft 365 Publisher, identify and gather all your important .pub files to ensure they are backed up and ready for testing in alternative software or perpetual-license versions.
Migrate to Publisher 2021 (Perpetual License)
Continue using Publisher 2021 to open and edit existing files without an active subscription.
Publisher 2021 is a perpetual-license (one-time purchase) version of the software. While it will continue to run locally after the Microsoft 365 version is discontinued, it will not receive ongoing feature updates or cloud collaboration improvements.
It should open most files created in newer versions, but documents utilizing the latest Microsoft 365 templates or advanced formatting may experience compatibility issues.
Save copies of your existing .pub files to a secure local drive or an alternative cloud storage platform to prevent data loss.
Ensure your perpetual license of Publisher 2021 is properly installed and activated on your computer.
Open a few complex .pub documents in Publisher 2021 to check for any lost formatting, missing fonts, or unsupported features.
Export Publisher Files to Alternative Formats
Convert your .pub files into standard formats like PDF or Word for long-term accessibility.
