Guest user activity

Hi Adam!

Thanks, yeah I believe I've seen that article before and it deals more with Guest users within certain teams.

My ultimate goal was to reduce the number of Guest users in my tenant, as it appears to be getting out of hand. 

With this, I was hoping to see if the Guest user hasn't logged in within a few months or a year we can simply delete them. 

I did find this sign in log tutorial: https://docs.microsoft.com/en-us/azure/active-directory/reports-monitoring/tutorial-signin-logs-download-script

 
But i believe its only checks up to a month if I recall correctly.
