Kai-L -- Microsoft Project is most certainly NOT transitioning to Planner. Project Online is being decommissioned on September 30, but Microsoft Project is NOT going away. If you think Planner can take the place of Microsoft Project, you are surely wrong, as the feature set in Planner is NOWHERE CLOSE to the feature set in Microsoft Project, and probably never will be. Please STOP telling people that Microsoft Project is going away, because it IS NOT!!!
No one here knows which add-in you are referring to. There is documentation (from Microsoft) for every update (from Microsoft) but you need to know the correct name and/or number of the update to search for its documentation.

Dear @Dale Howard [MVP],
Thank you for pointing that out and for the clarification, I truly appreciate it.
Just to clarify on my side, I was referring specifically to Project for the web and its transition into Planner for the web, not the Microsoft Project desktop application, which as you correctly stated, is not going away. I’ve updated my original answer to make that distinction clearer and avoid any confusion.
I truly appreciate you taking the time to correct and clarify this for the community. Your expertise and contributions are always valuable.
Wishing you a wonderful day.
Dear @Dawn P,
Thank you for reaching out to Microsoft Q&A forum.
Correct me if I'm wrong, I understand that you’re asking about a recently released Add-in for Microsoft Project? Based on my research, as of February 26, 2026, there is no standalone Add-in specifically for Project or Planner. The available Add-ins are primarily for Office applications. Could you please provide more details about which specific Add-in the customer is referring to? There are various Add-ins for Microsoft Office, Project, and other business tools, and the changes may vary depending on the version and product.
Additionally, if you're asking about updates for Microsoft Project, please note that Microsoft Project for the web has transitioned to Planner for the web, and Project Online will be officially retired on September 30, 2026.
For updates on Microsoft 365 apps, Microsoft provides detailed release notes, which you can find here: Update history for Microsoft 365 Apps (listed by date) - Office release notes | Microsoft Learn
If you can provide more specifics about the Add-in in question, I’ll be happy to assist you further in identifying the changes and finding the relevant documentation.
Looking forward to your reply.
