Remove Reminders
Starting from Outlook 2007/2010, reminders are supported in any Outlook folder and sub-folder. If you don’t want the reminders for items in certain folders to appear in your list of reminders, you can remove them.
To remove a reminder from the shared folder:
1. Open Management Panel.
2. Select the shared folder where you want to remove reminders.
3. Click the "Advanced Actions" button, and choose the "Remove Reminders..." option there.
You can also remove reminders from any Outlook folder by right-clicking with your mouse on the folder in the Outlook Folder List panel.
NOTE: Please be aware that after you remove the reminders as described above, you won’t be able to undo this action.
