Error when you try to remove or make a change to a distribution group by using Exchange Control Panel in Office 365: "You don't have sufficient permissions"

When you try to remove or make a change to a mail distribution group by using the Microsoft Exchange Control Panel (ECP) in a Microsoft Office 365 environment, you receive the following error message:

This issue may occur if the�ManagedBy attribute of the distribution group is empty or is configured for a user who is no longer active in Exchange Online. This issue could be caused by one of the following conditions:

• You do not have sufficient permissions.

• You transitioned from Microsoft Business Productivity Online Standard Suite (BPOS-S) to Office 365, and the Owner permission is no longer set for the distribution group.
• You are assigned the "Security Group Creation and Membership" role in the ECP. However, you cannot remove the distribution group.

To resolve this issue, follow these steps:
