Oftentimes, users share mailboxes through Exchange. This may be quite handy in many instances. For example: a personal assistant may read and reply to E-mails directed at company’s CEO.
There are times when being able to impersonate someone is advantageous. An information mailbox can be shared between many people who reply to customer service requests, brochures and other common requests without having to reveal their own email. In other cases however, due to legal, ethical or other concerns, it’s best to make sure that the recipient is aware of exactly who they are receiving mail from. For this reason we have ‘Send as’ and ‘Send on behalf of’ permissions.
Send As permissions allows the sender to impersonate the person who owns the mailbox. Send on behalf of permissions on the other hand, make sure that the real sender is identified by appending the words ‘Sent on behalf of‘ to the user name in the message header. Here’s how to set up Exchange 2010 in either case.
Whichever method you choose, you will need to have Outlook display the from: field so that you can toggle back and forth between senders. In Outlook 2010 & 2013, select options when creating a new message and click on the from icon. This will display the from field where you can choose from multiple email addresses to send from, provided that you have permission.
