This is using MS Exchange 2013 server. In ECP, when I tried to configured one mailbox to be in-place hold or Ligitation, the following error messages appear:
Unable to execute the task. Reason: The discovery mailbox, a hidden default mailbox that is required to search mailboxes, can't be found. It may have been inadvertently deleted. This mailbox must be re-created before you can search mailboxes.
I run "get-user -arbitration", and won't see any system mailbox. What should I do to be able to configure in-place for any mailbox.
Thanks in advance.
