How to change default email in Outlook to send email from ACT

[acters]

I use ACT V16.0.291.0 and Outlook 2013.

I have 1 Host Exchange Email Accouint - just added my Yahoo email to Outlook.

I send lots of "merged" emails.

Right now, emails are sent through the Exchange Email account be detault. How do I change the default email so merged emails are sent through the Yahoo email account?

Menu - FILE - Account Settings (The first square)  -  Account Settings

Select the account you want to use for Mail Merge - Temporarily set it to Default  (Set as Default Option)

If desired, after this configuration, restart Outlook to be sure.

Best regards...

Thanks.

I changed the default account in Outlook, exited Outlook and went back in.

Created a merged email but it was being sent from the original Exchange email account.

Must anything be changed in ACT itself?
