How to Resolve: Unable to Receive Weekly Digest for PIM
If you are not receiving the weekly digest emails for Privileged Identity Management (PIM), you need to make sure that you have a valid “Email” or “Alternate email” configured. Once the email is configured, Global admins, security admins, and security readers will automatically receive weekly digest mails.
As an administrator, you can choose the users assigned to receive the email and configure the weekly digest email in the Microsoft Entra admin center > Protection > Identity Protection > Weekly digest. The users need appropriate permissions to view any linked reports. https://portal.azure.com/#blade/Microsoft_AAD_IAM/IdentityProtectionMenuBlade/WeeklyDigest
If a user is enrolled in PIM to elevate to one of these roles on demand, then the user will only receive emails if they are elevated at the time the email is sent.
Of course, users must also have valid licenses assigned to make full use of these features. https://learn.microsoft.com/en-us/entra/id-governance/privileged-identity-management/pim-getting-started
