Why Are Tasks Locked?
Task locking is a data protection mechanism that prevents
conflicting edits while an approval is pending. Since the workflow request
captures a specific set of proposed changes, allowing further edits during the
approval process would invalidate the request and create data conflicts.
What Happens When a Task Is Locked?
• The task appears with a lock indicator in the Planner
• Edit icons and fields are disabled — no user can make
changes
• Even Project Administrators cannot override a
workflow-locked task
• The lock applies to all tasks listed in the pending
workflow request
How to Identify Which Workflow Locked a Task
Navigate — Planner →
Planner Options → Workflow → Received or Sent Tab
Filter — Set filter
to Pending to see all active workflow requests
Review — Open the
workflow to see the full list of locked tasks and their WBS numbers
How Are Tasks Unlocked?
Action | Result |
Approver
Approves the Workflow | Tasks unlock
— proposed changes are applied |
Approver
Rejects the Workflow | Tasks unlock
— original values are restored |
Requester
Withdraws the Workflow | Tasks unlock
— no changes are applied |
What Should You Do If a Task Is Locked?
• Contact the requester who submitted the workflow to
understand the pending change
• If you are the approver, review and act on the request
promptly to unblock the team
• If the request is outdated or incorrect, the requester
should withdraw it
• Do not attempt to delete or recreate tasks to bypass
locking — this can corrupt project data

When an Approval Workflow request is raised,
all affected tasks are automatically locked. No user — including authorized
users — can edit these tasks until the workflow is resolved. This article
explains how locking works and what to do.
