First of all, if you're a Oneflow-User, check with your Oneflow-Administrator to make sure you have permission to view all contracts.

If you do have permissions, you should be able to view your colleagues' contracts in the archive-view.

Contracts are stored per Collection, so if your company has multiple Collections, you should also make sure you have permissions to the correct one. You can see the different Collections you have access to in the drop-down at the top of your dashboard.
