Any d!NK publication can be shared (emailed or add to the Account Hub) from the app.
For PDF publications, sharing from the app is enabled by default. Sometimes, you want to restrict sharing of some PDFs. Here's how.
We have 2 scenarios for this:
1. Disable the sharing function for the entire enterprise.
This can be done with the sharing enabled checkbox in enterprise settings. Uncheck it to disable the sharing function on your app.
2. Disable the mail function for certain documents.
If this is the case you can uncheck the mail allowed in the publication settings.
Select your PDF document - settings - uncheck "Allow sharing".
Please note: all publications set to 'confidential' are not allowed to be mailed. As explained here.
