Permission to send

If you already have access to incoming emails from the shared mailbox, distribution list, group etc then in most cases you have permission to send as well.

For other people's mailboxes, by default you do not have permission to send as them. The IT Team will require direct authorisation from the person you are trying to send before permission is granted. Please ask them to specify which option of sending is allowed.

After sending your first email, if you receive a bounce back saying you don't have permission please raise a support ticket.

'Send as' vs 'Send on behalf of'

There are 2 methods of sending:

1. Send as sends the email from the email address you have used. For example:
   
2. Send on behalf of sends the email from the email address you have used but displays a message to the recipient that you have sent the email on behalf of the other person, distribution list or group. For example:
   

The permission for either option is set by the IT Team. Please specify which option you would like to use or, for other people's mailboxes, specify this in the authorisation.
