Is there a simple method for identify Azure AD Guest accounts that haven't been used or accessed in XX number of weeks/months?
Simple way, either via GUI or PowerShell, to identify "stale" or unused Azure AD Guest accounts?
Not sure if it meets your criteria of "simple", but you can use the Graph API to get each user's signInActivity property. You can use this to create a report, or filter based on specific timeframe (see example 5 here: https://docs.microsoft.com/en-us/graph/api/user-list?view=graph-rest-beta&tabs=http#example-5-list-the-last-sign-in-time-of-users-in-a-specific-time-range)
