I'm building an Outlook macro that sends email contents to an Excel spreadsheet. It's working perfectly up to the point where Outlook passes control to Excel.

By virtue of focus I cannot get my Excel macro to seamlessly begin executing after the Outlook macro execution finishes with the summon command, "Run [Macro name]"

I know I can set focus on other applications, I'm just unsure how to go about that. I've poured over documentation from Microsoft and I'm having a terrible time digesting the information and making use of it.

TL;DR: I need to set focus on an Excel workbook from an Outlook macro.

Guidance is deeply appreciated.
