One popular feature of the Microsoft Outlook calendar is the ability to receive reminders for scheduled tasks and appointments. If those reminders begin appearing at incorrect times or stop appearing at all, the reminder option is likely disabled or the file is corrupted. By checking the status of the feature, enabling it if necessary and fixing corrupt entries, you can fix this issue and reinstate correct reminders in Outlook.
Start Microsoft Outlook. Go to the "Tools" menu in Outlook 2003 or 2007 and select "Options." Select "Other," click the "Advanced Options" button and choose "Reminder Options." In Outlook 2010, go to the "File" tab and click "Options." Select the "Advanced" tab in the left pane and find the "Reminders" section.
Make sure that the "Display the Reminder" check box is selected in Outlook 2003 or 2007. In Outlook 2010, make sure the "Show Reminders" check box is selected. Click "OK." If the check box was not selected, enabling it will fix the problem. If it was already selected, continue on to fix corrupt reminder files.
Exit Microsoft Outlook. In Windows XP, click the "Start" button and select "Run." Type "outlook /cleanreminders" into the Open box and click "OK." In Windows Vista or Windows 7, click "Start" and type "outlook /cleanreminders" into the Search box at the bottom of the Start Menu. Select "Outlook/Clean Reminders" from the result list. Microsoft Outlook opens.
Check to see if your Outlook reminders are now working. If so, the "Outlook /Clean Reminders" switch has fixed the problem. If not, continue on to the final step.
Click the "Start" button and select "Run" in Windows XP Type "outlook /resetfolders" into the Open box and click "OK." In Windows Vista or Windows 7, click "Start" and type "outlook /resetfolders" into the Search box at the bottom of the "Start Menu." Select "Outlook/Reset Folders" from the result list. Microsoft Outlook opens with the missing or corrupt reminder folders restored.
