Outlook Calendar and Task reminders do not appear as expected

In Outlook, Reminders are associated with tasks and deadlines. However, reminders are versatile and can be used with calendar items, e-mail messages, and contacts as well as tasks.

Your Outlook Calendar or Task reminders may not appear at the scheduled time. Also, you may receive the following message when you click Save and Close for a new appointment with a reminder:
The reminder for may not appear because the item is not in your Calendar or Tasks folder. Is this OK?


The following are four common causes for this behavior:

Microsoft Outlook is not running. Unlike Microsoft Schedule+, which has a separate file to handle reminders, the main Outlook program controls the reminders. If Outlook is not running, reminders do not display.
The Calendar or Task reminder is not in your primary folder. Reminders only trigger from within the primary Calendar or Task folders. Primary folders reside where you receive messages. When you set up an e-mail service, you designate either your mailbox Inbox or your personal folders (.pst) file Inbox as the mail delivery point.

For example, if you receive messages in your personal folders (.pst) file Inbox and you create an appointment reminder in your mailbox Calendar, the reminder does not
display. If you create the same reminder in your Personal Folders Calendar, the reminder does display at the appropriate time.

Note Reminders trigger from other Calendar and Task folders in Microsoft Office Outlook 2007.
The Delivery option of your e-mail service is set to "None" (without quotation marks). You must specify a default delivery location for reminders to be processed.
The Reminders folder is damaged or contains corrupt reminder items.

Use one of the following to work around this behavior:

If Outlook is not running, start Outlook, and keep Outlook running to receive reminders.
When you create reminders, verify that they are saved in your primary Calendar or Task folder.
Exit Outlook, click Start, point to Run, type outlook /cleanreminders, and then click OK.
Exit Outlook, click Start, point to Run, type outlook /resetfolders, and click OK. Use this method if the /cleanreminders switch does not resolve the problem.
