I have the following problem. For some reasons we need to create a new task list in sharepoint. The task is created via the template. We would like to inform the users, when sombebody creates a new task and assign the task to a specific person. The function "E-Mail Notification, Send e-mail when ownership is assigned or when an item has been changed." is working fine for that demand.
Here is my problem: We would like to copy all finished or withdrawn tasks from the old task list to the new one. Even if I copy/paste all the old task via data sheet view to the new list, sharepoint sends an email for every copied task to the user. In the end, a few hundred mails would be send to the user because of the "new" ownership for the old tasks.
So I tried the following: I disabled the mail-when-new-ownership feature and copy/pasted all the old finished tasks in the new list. Still, after reactivating, Sharepoint sends all the mails.
My last try: I once disabled the mail-when-new-ownership feature and copy/pasted all the old finished tasks in the new list. Then I created manually a new task in the new list and assigned it to me. Afterwards, I reactivated the email-feature. It seems like it is working: I am the only one, who gets an email for a new ownerships. Sharepoint ignores the old stuff.
My question: Am I just lucky or is this a possible solution for my problem? Deactivate the feature -> Copy paste the old stuff -> manually create a task, assign it to me -> reactivate the feature. I hope, sombeody could reproduce my problem or could confirm the suggested solution. Thank you very much!
