Sharepoint list item @ comments disabled?

Question

Users reported that since yesterday the @ from the sharepoint list item is not sending the usual email after mentioning someone.

Has this function been disabled? I noticed that Sharepoint Alerts will phase out in Jun 2026 and that in Jan 2026 it's been slowly deactivated. So maybe that's why??

Answer 1

Hello @Mata Ricardo,

I noticed today that this issue has now been officially posted in the Service Health dashboard (ID: SP1220310).

According to Microsoft, a recent service change caused some users mentioned in SharePoint List comments to stop receiving email notifications. At the moment, the engineering team is actively reversing the change and will provide a timeline for completion once it becomes available.

If there are any further updates from Microsoft, I will share them with you as soon as they are published.

Hello @Mata Ricardo,  

Thank you for reaching out to the Q&A forum! 

After receiving your information, I did some additional research and also checked the Service Health dashboard. At the moment, there are three active incidents related to SharePoint, but none of them mention any issue related to @mention emails not being sent. 

However, as you mentioned, I found this post where many other tenants are experiencing the exact same issue starting this week: @mentions not sending any emails from a microsoft list - Microsoft Q&A

Because many organizations are reporting the same issue at the same time; I believe this should be reported to the Microsoft product team as soon as possible. 

If this is a work account, I strongly recommend take the following steps:  

Note: If you are an end user, please contact your IT administrator to perform these steps.    

1.Report the issue through the Microsoft 365 admin center: (Recommended)

When multiple tenants report the same problem, it helps the development team investigate. If it’s confirmed as an incident, it will be published in the Service Health dashboard.      

2.Raising a support ticket to reach out to higher technical: 

Additionally, if you would like more detailed technical verification or confirmation from higher‑level engineering teams, you can also raise a support ticket through your Microsoft 365 Admin Center: 

• You can go to: Microsoft 365 admin center                    
• Please follow this article: Get support - Microsoft 365 admin | Microsoft Learn
• On right bottom corner click on "Help & support"

Regarding your question about whether this issue is related to the retirement of SharePoint Alerts, I would like explain detail:

Since there is no official communication from Microsoft, I cannot confirm the exact cause at this time.  

However, it is important to note that @mention comments in Microsoft Lists/SharePoint do not rely on the classic Alerts system. They use the SharePoint notification service, which is still active and might be not part of the retirement plan.

Once again, I sincerely apologize as I understand this issue may impact your workflow. However, I hope you understand that as a forum moderator, I do not have access to the product team’s back-end systems.  

However, I will continue checking Service Health daily. If this issue is published as an official incident, I will update you immediately. 

Looking forward to hearing from you!
