When I create invoices in Office/Dynamics365 I don't seem to be able to select one of my account email aliases as the send from address. Everytime I select send from address it wants to me to log into a different Office 365 account. We have several business names with different domain names and websites that we all run through one corporation. We want the invoices to be branded with each "sub company" logo and appear to come from branded email address even if they all go into the same inbox.
