In some cases, when generating a report that depends on Entra ID Report Data, you may see the following error message:

Starting September 1st, 2021, Microsoft has enabled anonymization of Entra ID Report Data as the default setting in all tenants. More information is available here.
If you wish to use EasyEntra Reports that utilize Entra ID Report Data, you must disable the anonymization of Entra ID Report Data. Ensure you are in compliance with company and regional regulations before doing so.
To disable Report Data anonymization, go to Microsoft 365 Admin Center, select Settings -> Org settings -> Reports, deselect the option ‘Display concealed user, group, and site names in all reports’, and click Save.

The setting takes effect immediately.
