Unable to reassign the group at this time

Error Message

In ArcGIS Online, when attempting to change the ownership of a group to a member in an organization, the following error message is returned:

Error:   
Unable to reassign the group at this time.

Cause

The following are known causes for this issue:

• The member’s default role or custom role has insufficient privileges.
• The member owns an existing group with the exact same name as the reassigned group. A member must not own two groups with the same name.
• The ownership of a group with update capabilities is transferred to a non-administrator member.

Solution or Workaround

Depending on the cause, use one of the options below to resolve the issue.

Note:
Only an organization's administrator can perform the following workflows.

Update the member’s role to enable the privilege to own a group

Note:
A role defines the set of privileges assigned to a member. Privileges are assigned to members through a default role or a custom role.

• Change the member’s role to a default role such as User, Publisher, or Administrator, with the privilege to create groups. Refer to ArcGIS Online: Change member roles for more information.
• Update the member’s custom role to enable the privilege to create groups. Refer to ArcGIS Online: Configure member roles for more information.
