Short Version
Microsoft is phasing out the SharePoint Alerts feature in favour of Power Automate. Phased retirement: July 2025 to July 2026.
Details
SharePoint Alerts are being retired. Microsoft 365 suggest you use Power Automate platform or SharePoint Rules instead. Owners of existing alerts should note the October 2025 date.
Timeline (source Microsoft.com):
From July 2025: The creation of new SharePoint Alerts will be gradually turned off for newly onboarding tenants.
From September 2025: The creation of new SharePoint Alerts will be gradually turned off for all tenants.
From October 2025: The SharePoint Alert expiration feature will be gradually activated. Once activated, any SharePoint Alert will have a validity of 30 days starting from its first run, then it will expire. Users can self-service re-enable expired SharePoint Alerts and extend their expiration for another 30 days. Re-enabling and extending SharePoint Alerts can be done by using the Manage my alerts list/library menu item, opening the SharePoint Alert to update, extending its expiration date and clicking OK.
July 2026: Microsoft will remove the ability to use SharePoint Alerts, existing SharePoint Alerts cannot be extended anymore and will not work anymore.
