Your school determines how long a transcript should be available before it expires as well as whether or not you can print it and how many times it can be viewed. These document controls are applied as a safeguard to help protect student information.
The email you received containing the link to the Transcript Download Center lists the security settings or document controls that have been applied to your electronic PDF transcript, including expiration date, whether or not printing is permitted, and the number of times the transcript can be viewed.
If your transcript has expired, you will need order a new transcript (or ask the requestor to order one, if you are the recipient of a transcript other than your own). The settings cannot be removed or edited.
