When you want to change the default to another mailbox to which you also have Full Access permissions, then you can configure your mail profile with that mailbox instead and add your own as a delegate mailbox. Method 1: Change default to Delegate or Shared mailbox


Method 2: Configure an additional Exchange account.Method 1: Change default to Delegate or Shared mailbox.This guide instructs you how you can cope with the above scenarios via built-in Outlook account configuration options and settings but also provides a code sample to set the From address programmatically. While you can manually specify the From field to send from each time you need to send out as that address, when needing to do that becomes the rule rather than the exception, it’s time to automate things. For instance, when you work in support and need to send out from the central support address rather than your own or when you represent a manager. However, in some situations, it is not uncommon that you need to send out as this mailbox or distribution group more often than from your own name. When you have permissions to “Send As” or “On Behalf Of” another mailbox or Mail Enabled Distribution Group in an Exchange environment, you can use the From field in Outlook to specify this.
