The dates, and what they mean for you.
| Date | What happens | Who it affects |

If you use Microsoft 365
If Publisher still opens on your computer, export important files to PDF now. You can do this one by one or use Microsoft's free sample PowerShell script for a whole folder. The script needs a working, licensed Publisher installation. Once Publisher is removed from your Microsoft 365 installation, you'll need another way to open .pub files.
If you bought Publisher 2021
Publisher keeps running after 13 October, but without security updates or fixes. It's a good moment to export the files you care about while everything still works.
