Last updated on
Jun 7, 2026
Learn how to apply security policies for Outlook attachments using Adobe Acrobat.
Applying security policies to Outlook attachments helps protect files before you email them. It ensures recipients can access attachments only according to the defined permissions.
Before you begin
This option is available only if Adobe Experience Manager – Forms Server (Document Security) is set up and available in Acrobat.
Select Attach As Secured Adobe PDF on the Adobe PDF ribbon.
Select the file you want to attach by typing the file path or selecting Browse.
Specify how you want to secure the document from the available security options, and then select OK.
The file is converted to PDF and encrypted using the security method you choose.
Complete the email message, and then select Send.
