Thanks Graham, that'll be great instead of checking back and updating my lists.
I've created an additional split tunnel policy to take place first before any other policy for VPN, logged off all of my office products and then logged off the VPN. Established a new VPN session, opened office.com, authenticated and then opened Outlook, word, etc...
I can see my VPN IP sending office logs over the new policy, however when I look in sign-in logs within Azure AD for those new sign-ins, it still shows my home internet IP as the IP that was used rather than my corporate IP's for the split tunnel policy. I'm baffled by this. Short of utilizing a full tunnel for VPN instead of split, I'm not sure how else to accomplish this.
When I had a ticket open with support, they didn't indicate anything about the ISDB you provided so I'm not sure how to proceed to get this completed. Thanks!!
