Created a mail in the Mail Module instead of the package? This article shows you how to link an existing mail from the Sent folder, and how to remove them. You can also link from the Inbox folder.
After selecting the mail in Sent items and clicking Link to Packages, a pre-filtered Package Register will open. This only displays those packages where you are either the Package Administrator or Editor, and where the Package Types has Mail creation enabled. It also only displays open packages. If you want to link a mail to a closed package, you’ll have to reopen the package. You can filter this list by Package Number, Title and Type.
