You can now setup transactions to allow them to be forwarded to other MX users.
This means as the sender you can go back and add more recipients after the data has been sent, but also that your recipients can forward data as well.
As sender
The transaction number stays the same and you will continue to have visibility of the transaction throughout its onward path to other users. You continue to have the ability to 'revoke' any future recipient, preventing them from downloading the data.
If the data is sensitive, leave the option switched off and forwarding will not be possible.
To allow forwarding, tick the option highlighted in the image below on the Send page.
As recipient
You will have visibility of the originating user / company and the original transaction contents (existing functionality).
In addition, you will have the ability to forward to another MX user inside this MX customer; internal users can forward to anyone, external users can forward to internal users and any user who is in the same external organisation (i.e. your colleagues in the same organisation name).
On the download page (as the sender or recipient), you can select 'add recipient'.
Add a new comment that will be emailed to the new recipients.
Search for user(s) in the address book.
Click Add Recipients to forward the data.
