Administrators are provided the necessary tools to control and even limit the Alerts capabilities in accordance with the established corporate rules and regulations.
The administrative settings are tightly integrated into the app and available to site collection and Global administrators as an extra tab on the same Alerts page (for site collection-scoped settings) and within Global Settings (for tenant wide settings). Using these settings, admins are able to completely prevent regular users from creating alerts, limit the mail template creation, specify authorized From account and configure many other settings.
You are able to configure tenant-wide settings that are only accessible to Global or SharePoint administrators. Accessible through the dropdown menu on the right-hand side of the toolbar, under your initials.
This establishes the company-wide policy, with or without giving the site collection administrators the right to override those settings at the site collection level.
If the tenant-wide settings are set not to allow overriding, site collection settings would be blocked and immediately stop being used, even if they were defined.
Please note that to be able to see the Global Settings option, the current user must be a Global or a SharePoint administrator in the tenant. If you installed the app prior to 1/1/2025, you might need to grant access to Entra ID once under Alert -> Administration from any site collection by a Global Administrator. It will ensure the app can check user permissions
