...
To change the permission for a message, create a New Message, click Encrypt, then click Change permissions. Select the appropriate encryption type from the dropdown list. The four types of encryption are:
| Expand |
|---|
| title | Encrypt-Only (or simply "Encrypt" in Outlook web) |
|---|
|
 - Messages that have the encrypt-only policy applied can be read directly in Outlook on the web, in Outlook for iOS and Android, and Outlook for PC versions 2019 and Office 365.
- When Encrypt is first selected as an option while drafting an email, this is the default setting providing standard O365 encryption for email transporting within Cal Poly (@calpoly.edu). Recipients external to Cal Poly will receive a message with a link provided. That link will take Office 365 users to Outlook on the web to read their message. Users with other email accounts (e.g. gmail) will be prompted to go through a process to obtain a one-time passcode to read the message in a browser window.
