I use Outlook for my email client, for several external email addresses along with my ISP address in Verizon. When doing a mail merge, I want to use one of the "other" email accounts, NOT the Verizon one (which is the first/main). Unfortunately there is no option to choose which account the emails go out under unless I missed it. I ran the mail merge and it went off successfully but the account the emails went out under was the ISP account with Verizon. Since these emails are pertaining to a company to which I have an internal email address, I wanted the emails to go out under that account instead. I have that account as one of the accounts in Outlook. I also had it set to "Default" but still the emails went out under the main email account.
Please help.
