This feature is available in all editions
The Edit link on an item isn't active (is grayed out) even though you are the owner of the item.
There are two possible reasons for an item not being editable. To figure out which reason, ask: Is it all or just some of the items you can't edit?". If the answer is:
|You cannot edit any items in the project||The project role assigned to you for the project does not grant permissions to edit items||Ask your project administrator to change your role to one with a higher level of access. Refer to Roles & Project Membership for more information.|
|You can edit some items, but not all||The item you are trying to edit is closed or the sprint that the item was part of is closed.||Re-open the items you'd like to edit or re-open the sprint they were part of.|
