Add passwords to mail merge

The add-in can retrive individual passwords using a merge field from a datasource. Or you can set the same password for all files manually.

Adding separate passwords to mail merge letters

An attachment can have two types of passwords:

  • Password for viewing, required to open a file.
  • Password for editing (also known as a permissions or master password) to prevent users from changing PDF and DOCX attachments.

Moreover, when sending PDF attachments, Mail Merge Toolkit allows managing permissions for printing, editing, and copying attachment content. Recipients don’t need a password to open the document, but they do need a password to change or remove set restrictions.

  1. Situation is: I got already prepared PDF files, with passwords. I need to create a custom message, put that PDF into a ZIP with password, add this as attachment and send – would that be possible?

  2. Please could you direct me to the help sheet to change sender details. Is it possible to send the mail merge ‘on behalf of…’ another account or even change to ‘send as…’ on behalf of another Outlook account. Thank you

    1. UPDATED: Mail Merge Toolkit allows selecting one of the sender account configured in Outlook. To activate this feature go to the Sending settings tab and select Ask for the email account for sending messages. This will prompt the account selection before starting the mail merge.

      Additionally, you send mail merge messages as someone else, if you were granted a permission to Send As or On Behalf Of another Exchange mailbox.
