UConn faculty and staff may attach their OneDrive files to outgoing Outlooks emails. This method is akin to the well-known method of attaching a file to an email.
ITS recommends that you instead use the Share link option by following this guide: Send OneDrive Items in Outlook - Encrypted File Transfers
The method of sharing in the guide linked above generates a link to the item, it does not send the recipient(s) the file itself. Creating a link ensure the file remains encrypted; the recipient will need to sign into their Microsoft account in order to view/edit the item. When the user opens the file, you are both editing the same file while changes are saved to a single file on your OneDrive. If you are working on the file at the same time, you will see updates by each user as they are typed.
The method shown on this guide will send an unencrypted version of your OneDrive item.
This file will be separated from your OneDrive; any updates made to the attached file will not be reflected in your file in OneDrive. This method uses no more security than a regular, secure Outlook email.
