Script external-identity-research-JUL2020.ps1 incorrectly reporting static group membership guest users

Dear,

Running the script I noticed that guest users that belong to either managed or consumer domains and are part of static groups (either 365 or Security), appear in the HTML report, when it is supposed they should not, since the report shows External users that have no static group membership or application assignments in your tenant.

Do you have any idea of what could have happened?

Thanks for your help.

Regards,
