Microsoft Project Service Core Jan 2026 Update locked Plans table
We recently noted the Microsoft Project Service Core was updated to 1.0.161.1772:
This update has locked our Plans table, no changes are allowed to the forms and creating new columns is greyed out:
We cannot make use of Planner in our model driven app (Planner Premium, non-default environment). After a new Plan is created, the user receives this message when opening the Plan:
Two days ago we were in this version 1.0.160.2874):
and everything was working as expected.
Any guidance would be much appreciated as we are not sure if this is a permanent lock or once the update cycle is completed we will be able to go back to edit Plan forms and columns.
Thank you in advance
Hi Bridgeburn
According to our ticket with Microsoft:
A bug has been identified in Project Operations (PO) version UR62 — 4.161.0.1688 and PS Core version 1.0.161.1722. Microsoft has acknowledged this bug.
The Microsoft support team clarified that:
- Microsoft can run a backend script to address the issue, and this may take up to 48 hours to take effect.
- However, the script is only required if you are already on the fixed version and the issue persists, which matches your scenario.
Fixed version:
The first released version after the affected build (4.161.0.1688) is Dataverse 4.162.0.962 (January 2026), which is the fixed version that resolves the issue. https://learn.microsoft.com/en-us/dynamics365/project-operations/whats-new/whats-new-home-page
In our ticket we successfully got unlocked the msdyn_project table when the Microsoft support engineer run the script in two of our affected environments.
Hope it helps

We’re experiencing the same issue and are very curious to know what the solution is.
We’ve rolled this out to several customers, and now nothing can be modified in this table anymore, which is a major problem.
Same problem here at several customers! The msdyn_project / ,sdyn_plan table is the heart of the complete solution. Making this a managed table is a disater for any update or change to the solution. Microsoft needs to roll-back the update which makes the plan/project table managed.
