When I created a tasks' list on SharePoint and added tasks on it, SharePoint alerts sent notification mails to the team members mentioned in the 'Assigned to' column. However, when I try to add tasks now, it does not send the notification mails. I have not changed any settings and the 'Send e-mail when ownership is assigned?' is set to 'Yes'.

Have you configured your outgoing email settings in central administration. Are you receiving any mail from your sharepoint server, like for example, if you assigne some permission to users are thery receiving emails?Thanks & Regards, Neerubee

Yes they are receiving other emails. I set up a workflow and all the users received an email.

Hi PCpoint, 1)Open the list and click on Settings | List Settings 2) Click Advanced Settings 3) Change the Email notification to No and press OK 4) Click Advanced Settings 5) Change the Email notification to Yes and press OK Check whether you set item level security, if so, disable it, then check the effect.
