Shared mailbox: reasons for using, features and how to activate it.

Shared mailboxes allow users to share their mailbox with other users in order to view and send email from a common mailbox. These accounts work in the same way as a normal email account but can be managed by several people.  There is only one owner of the account.

Why using a shared mailbox?

  • A shared mailbox is ideal to organise info@ or support@ generic addresses that are managed by several people in an organisation
  • A shared mailbox allows you to delegate the management of your email to a personal assistant or colleague you trust
  • In case of email lists, a shared mailbox could allows you to store only one copy of mails as opposed to multiple copies

What are the features of a shared mailbox

  • A shared mailbox in a normal email account belonging to a user (account).  This user allows another user (or users) to manage their email just as if it were their own email account.
  • The users that gets access to an account have total access to this account.  All folders are accessible: Inbox, Sent, Trash, Templates,…  Users that get access can even search in the other email account.
  • Concepts such as Send on Behalf of or Send AS do not exist.
  • We plan to release shortly a feature that will allow users to make a specific signature for the mailbox they get access to.  This will allow them to inform the recipients of the emails that they send that the email was sent ‘on behalf of’, ….  In order to do so, the shared mailbox will have to be added to the Personal Data of the account.
