Outlook 2016 VBA to alert user with pop up message
 

Hi

This is the issue:

I need an Outlook rule for emails I send to pop up an alert if specific words in the subject is found and specific email in the To field is missing.

Standard Outlook rules do not provide this rule.

Can anyone provide me with a vba code for Outlook 2016 to have this rule implemented?

Thank you in advance for your help.
