Wondering if anyone has found a way to check on activity for guest users.
For instance, last time they even logged in or last password reset like the things you're able to find in MSOL.
Trying to scope out the inactive guest users.
The closest thing I can find is the WhenChanged attribute within their mailuser and even that value is a bit unreliable.
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.
Guest activities should be recorded in the Office 365 Unified Audit log, just like with regular users. On the Azure AD side of things, you can check the Sign-in logs, which you already found, and the Audit logs next to them.
