Cannot Send Messages from Shared Mailbox

Issue/Question

I have added a shared mailbox account to Outlook but I am not able to send messages from the account. 

Environment

• Outlook

Cause

The From option does not appear when composing an email, so you are unable to send messages from the shared mailbox.

Resolution

For users with only one email account added to Outlook

1. Click New Email to begin composing a new message. 
2. Click From and select shared mailbox address. 
   Note: If you do not see the From field, click Options and click From.
3. If you do not see the shared address, choose Other email address and type the shared mailbox address. 
4. Click OK. 
5. Finish composing your message and click Send.
6. The sending address should be selectable from the From drop down list when composing future messages. 
   Note: When sending a message from a shared address, recipients will only see the shared email address in the message, not your personal address. 

For users with multiple email accounts added to Outlook
