Hello,
Thank you for posting in Q&A forum.
Due to the incompatibility between Windows Server 2019 and Microsoft Sticky Notes, it is difficult to achieve the goal of installing Microsoft Sticky Notes on Windows Server 2019. We apologize for any inconvenience caused.
You can look for third-party free applications to replace Microsoft Sticky Notes and ensure compatibility and security with your system before downloading and installing them.
I hope you can find an alternative solution smoothly. Please feel free to contact me if you have any questions.
Best regards,
Jill Zhou
