Using Classic Outlook on Windows for personal email, calendar, and contact management
Dear TSNorma Cruz.
Good day! Thank you for posting to Microsoft Community.
According to your description, the issue of your concern looks like you need to execute a specific macro code depending on which account an incoming email is addressed to if in Outlook.
I would very much want to assist you further but as exchange online public forum support, we have limited tools to troubleshoot this given issue, it is best for you to contact the Outlook developer tech support team by posting in - Office Development - Microsoft Q&A. Engineers who are dedicated into this environment with rich experience and more resources can then assist efficiently.
We believe they would conduct in-depth research on the problem you encountered and provide you with more professional assistance.
In the meantime, I would also like to invite community members and MVPs in the forum to share their knowledge or any workaround and insight on this topic.
Thanks for your precious time and your understanding would be highly appreciated.
Best Regards,
