Answers for private customers

The Knowledge Base for private customers is already largely up to date. A few individual articles are currently being revised and will be updated shortly. We thank you for your understanding and look forward to providing you with the latest information on using mailbox.

Please note: The Knowledge Base has changed slightly. Categories have been adjusted and any URLs stored in the old Knowledge Base are no longer valid.

Where can I find the PIN for external users

Note: To use the functions described in this article, you must have the mailbox Guard activated.

When you send an encrypted message to someone who does not have a mailbox account and for whom you have not stored a public key in the key management, a temporary mailbox at mailbox will automatically be created for that person. This ensures secure communication. This mailbox can also be protected with a one-time PIN, since the access link itself is transmitted unencrypted. You should therefore provide the PIN to the recipient via a secure side channel (e.g., phone, SMS, or in person).

Important: In the current interface, the PIN can no longer be viewed after sending. Unlike before, there is no longer a function such as “Check assigned PIN.” The PIN is also not permanently stored in the source text.
Therefore: Be sure to save the one-time PIN before sending the mail. Without this PIN, the recipient cannot access the temporary mailbox.

Please note: Temporary mailboxes are automatically deleted after 90 days of inactivity.
