Hi Sanaa Al-Tamimi,
Thanks for reaching out to Microsoft Q&A.
Yes, it is normal for a user without any Azure permissions to receive a notification about the expiration of a free subscription if they registered for one at some point, even if they don't have ongoing permissions or active roles. Azure sends these notifications as part of its standard process for users with expired credits or free subscriptions.
If this user registered for a free subscription using their email, Azure would notify them directly regarding the expiration, including the removal of associated data and services. However, if the user did not intend to subscribe personally, you may want to confirm that the subscription is indeed tied to their account or investigate any potential accidental or unauthorized usage.
