Hello, I am using Outlook 2011. I have 2 accounts - 1 x POP account set as default and one Exchange account. When I click New Email the new email window opens and the email is addressed from the non default account. Replies are the same ie if I receive an email on the POP account and click reply the reply is addressed from the non default Exchange account. I know that when selecting a new email and then changing the sending account does not change the signature associated with each account, as it does in Outlook 2010 Windows version, but the above problem renders the program almost unuseable as I am always having to deselct the account and then add in the signature every time I send or reply. Is this really a program Microsoft are charging money for? Anyone any solutions?
