Hi,
Since you have full access permission to the shared mailbox, you can add the shared mailbox in your Outlook profile as a second Exchange account. Then, you can use the following Macro to make Outlook to always send emails from the specified account:
Public Sub New_Mail()
Dim oAccount As Outlook.Account
Dim oMail As Outlook.MailItem
For Each oAccount In Application.Session.Accounts
If oAccount = "Name_of_Default_Account" Then
Set oMail = Application.CreateItem(olMailItem)
oMail.SendUsingAccount = oAccount
oMail.Display
End If
Next
End Sub
See the following article for more information:

Or, you can create a custom message form/template in Outlook with the From field set to the shared mailbox, and then create new messages using the custom form or template.
Hope this helps.
