Thanks! I will try this out and see how it goes. We were concerned about the differences in the two entries. The one has "a mx" and the other doesn't. We don't want to break the interaction to our company email. Do these variables just need to be before the "include:" and only adjust the entry they preceded?
v=spf1 a mx include:e2ma.net include:spf.protection.outlook.com -all"
The "a mx" part is usually before the "include" statements, but I don't know for certain that it matters where they are. You do need separate "include" statements for each mail server that might send mail on behalf of his domain.
Let me know if you run into any other hiccups here!
