Link an existing mail from the Sent folder or Inbox.
You can select up to 100 mails to be linked at a time. If you choose to link confidential mail, keep in mind it is only visible to the sender and recipients of the mail itself.
You'll only see open packages where you are either the Package Administrator or Editor, and where the Package Types have mail creation enabled. If you want to link a mail to a closed package, you’ll have to reopen the package first.
Select the checkbox to the left of the Status column, then click Remove.
