I created the workflow in sharepoint designer using Collect data from user option. The approver receives three automated mail.
1) Notification to approve - Task assigned email 2) After approval, task has been changed alert 3) Another task has been changed alert
Is there an option to suppress the last two task has been changed alert? I would like to send only the Task assigned mail to approver
I faced a similar issue and after a research i found a solution that works well for me. I have used Sharepoint Manager 2007 http://www.codeplex.com/. Just use it and do the following as in screen dump: http://sharepointburger.files.wordpress.com/2010/03/sp20071.png
The first "You've been assigned a task" email is a feature of the Task list template and can be changed in List Settings > Advance Settings > Send e-mail when ownership is assigned.
The second two emails are "Alert me" emails. (Not sure why you are getting two, I suspect you my have signed up with 2 different users accounts that could even have the same email address.)
To delete the Alert Me for the currently logged on user.
Actions > Alert Me > View my existing alerts on this site
Then select your alert and Delete.
By the way - this is not a programming related question (See FAQ top right) so you may get quicker answers by posting similar questions on sites such as superuser.com or SharePoint.SE
I guess that you created your workflow in a "Task" list that has the email alert to "Assigned To" enabled. You can disable this feature under Settings, List Settings, Advanced Settings.
Your approver likely has "Alert Me" features enabled for this list. You can delete these under Action, All Site Settings, User Alerts.
As a side note. Answer to the question this title sounds like it is asking: The "Send e-mail when ownership is assigned" feature in "Tasks" lists on SharePoint often causes problems by sending unwanted emails like the task has been changed alert this question refers to. For those of us who Own sites below the site collection level and do not have access to the top level. Here is a way to fix such problems.
Turn of the "Send e-mail when ownership is assigned" feature and design a workflow in SharePoint designer that mirrors this feature minus to portion of the functionality that is not wanted.
