I want to include a document in my mail merge. I cannot find an option to do this when starting the mail merge from Outlook or from Word. How can I do this?
There is no native way in Outlook or in Word to do this. However, you can use the Mail Merge Toolkit addin from MAPILab which adds this functionality (discount code: 4PM76A8).
Another way to do this would be to use a script which will add the attachment after the merge has completed. For this, you’ll need to put Outlook in Offline mode while doing the mail merge so you can manipulate the merged messages which are being held in the Outbox folder. An example for such a script can be found here.
