Consider the following scenario:
The Delegates settings were not saved correctly. Cannot activate send-on-behalf-of list. You do not have sufficient permission to perform this operation on this object.
This issue occurs because Role Based Access Control (RBAC) is involved in the decision whether the user has permission to perform the action. In the scenario that is mentioned in the "Symptoms" section, the user has permission on the non-user mailbox. However, the user does not have management rights over the non-user mailbox.
To resolve this issue, install the following update rollup:
