Decrypting PDF attachments

When archiving password-protected PDF documents, it is necessary to archive the password as well. Otherwise, these documents cannot be opened later. Losing your passwords means that you will not be able to access the PDF documents afterwards. This is where the Outlook Add-in helps you by removing the now no longer needed password protection from PDF documents. The function becomes active for an email with PDF attachments.

Proceed as follows:

1. Go to Start > Security.
2. Click Decrypt PDF attachments.

   NOTE: The Outlook Add-in first checks whether you need a password to open the PDF attachments. Then it tries to decrypt the password-protected attachments with the already saved passwords. For attachments that cannot be decrypted with the stored passwords, you will be asked for the password. If you do not know the password, you can skip the decryption for this attachment with Do not decrypt this PDF.

3. Enter the password.
4. (Optional) Click Save password for later useto add the entered password to the list of saved passwords if decryption is successful
5. Click Try this password.

Documents for which decryption failed are displayed along with their file name and the reason for the failed decryption. PDF files that are not password protected - and therefore do not need to be decrypted - are not included in this list.

A report is attached to the email for successfully decrypted documents. The file name used is PDF decryption report.txt.
