The messaging feature enables all users of a box to exchange Lockbox messages and emails. The history feature keeps a record of all activity in a given box.
Lockbox messages are broadcasts. This means that they are always sent to all users of a box.

To send a Lockbox message:
The message is sent instantaneously to all users including the sender.
The existence of unread messages is indicated in the Lockbox client. Recipients find a number in brackets that is placed in the box navigation pane just in front of the box name to whose users the message was sent. The number reflects the number of unread messages, e.g. (2) stands for 2 unread messages.

To read a Lockbox message:
Unread messages are highlighted with blue font colour.
If an unread message is selected, the 'unread messages' indicator in front of the box name is decremented, e.g. from (2) to (1).
If all unread messages are read, the 'unread messages' indicator in front of the box name disappears.
To delete a Lockbox message:
Messages are deleted instantaneously. They can not be recovered afterwards.

Follow the below steps to send an email to all, or a selection of, users of a box.
By default, an email is sent to all box users including the sender.
Emails are sent instantaneously. However, mail server settings and network conditions (outages, traffic, interruptions) along the send path may delay an email.

Box transactions, such as file uploads and downloads, are logged in Lockbox. The history provides you with an overview of any such transaction by any user in the form of a list. The history is for example helpful if you need to trace whether someone has accessed a new document or to find out who deleted a folder.
Lockbox recommends to set a small time range. In this way, the output is fast and you are not overwhelmed with a very long list of history entries.
