Permissions error during a multi-mailbox search in Office 365 dedicated/ITAR

Symptoms
When you try to perform an estimate-only multi-mailbox search in Exchange Control Panel (ECP), you receive the following error:

You don't have sufficient permissions to search the mailbox "<Domain>/Users/DiscoverySearchMailbox MailboxName" because it's outside the scope of mailboxes you can search. To get permissions, contact your administrator.

Cause
By default, the discovery search mailbox is selected as the target mailbox, and this mailbox is outside the recipient write scope for an Office 365 Dedicated/ITAR administrator.
Resolution
To work around the issue, follow these steps:
  1. Temporarily select the Copy the search results to the destination mailbox option under Search Name, Type, and Storage Location, and then select a discovery search mailbox that is within your recipient write scope.

  2. Reselect Estimate the search results, and then click save.
