Update: I have not tested this myself, but apparently the option now appears on the UI with April 2013 CU: http://social.technet.microsoft.com/Forums/sharepoint/en-US/8ee6bd15-6aae-43c1-a853-66ae6523adbc/assigned-to-email-alert-issue?forum=sharepointgeneral.
Update: Despite the link above, I tested this on SP1 with June 2014 CU and still could not find the option on the UI.
In SharePoint 2013 you will find that the option to enable email notification for Tasks list is no longer there. It used to be under List Settings > Advanced Settings > Send e-mail when ownership is assigned? (Yes/No). It is still there for Issues list in SharePoint 2013 however.
The good news is you can still enable it for Tasks list in SharePoint 2013, and it still works. The only thing is you’ll need to use PowerShell :). Use the script below to turn on email notification for a specific list:
Add-PSSnapin Microsoft.SharePoint.Powershell $web = Get-SPWeb "http://myServer/myWeb" $list = $web.Lists.TryGetList("Tasks") $list.EnableAssignToEmail = $true $list.Update()
Once email notification is enabled for the Tasks list, you will get the good old “The content of this item will be sent as an e-mail message to the person or group assigned to the item.” message when creating or editing an item in the list.
I’m guessing this is a MS bug. I have tested this on the March 2013 Public Update and the UI option for Tasks list is still not there.
Note: Before you run this code, make sure that you have configured outgoing mail for the web application though. The option to enable email notification for Issues list does not appear in the UI until this is configured. So it’s best to configure this before running the PowerShell code for Tasks list.
