CSSCurrent en:Revoke Transfer
General
After a transfer has been performed, there may be reasons to revoke access to the files of this transfer for all recipients, e.g. because
- the containing information is outdated and obsoleted by a new transfer.
- the transfer has been sent to the wrong recipient(s).
- it is required to revoke access for all recipients due to security or regulatory reasons.
How to revoke a transfer
Button on the summary page after sending a transfer
In order to revoke immediately after sending, users are able to use the button 'Revoke transfer' on the summary page.
Button in the sender notification
In order to revoke a transfer some time after sending, the user has to enable the option 'Send me a notification email about this upload' on the 'transfer options' page. After sending the transfer, the sender receives a sender notification mail, where he is able to use the 'Revoke' button.
When using the button in the sender notification mail, it may be necessary for the sender to re-verify themselves in order to prove that they are in fact the original sender.
