SharePoint agents retire in March 2027: migration paths and ownership actions
Diesen Beitrag auf Deutsch lesen
Existing SharePoint .agent files stop working after March 2027. Owners must review them and choose between Microsoft’s manual upgrade paths.
TL;DR
Existing SharePoint and OneDrive .agent agents continue working until the end of March 2027, then stop during a rollout through mid-April. From mid-November, Create an agent opens Agent Builder instead. Owners can use the SharePoint builder Upgrade button or a Copilot in SharePoint skill to convert agents manually, one agent at a time.

Governance takeaway
- Makers: Review each existing .agent agent and upgrade only those still used, because Microsoft’s conversion process is manual and agent by agent.
- Admins/CoE: Track the March 2027 retirement and the rollout through mid-April, because existing .agent agents will stop working.
- Leadership/Business: Confirm which agent experiences still provide value, since Agent Builder and Copilot in SharePoint cover capabilities that reduce the former SharePoint UI advantage.
