Outlook 2003 reminders not working

Posted on 2009-02-10
Last Modified: 2012-08-14
When opening Outlook 2003, one of my users is getting this error message:
"There was a problem reading one or more of your reminders.  Some reminders may not appear.  Cannot locate recurrence information for this appointment".
Reminders are not working and therefore not notifying the user.
I have tried running the /cleanreminders and /clearfreebusy commands but am still unsuccessful in resolving this issue.

    Try running the following command

    "C:\Program Files\Microsoft Office\Office11\Outlook.exe" /cleanreminders   (not if you installed office in another location you will need to change the path)

    I already ran outlook.exe /cleanreminders from the run command as I stated in my original post.  I also ran outlook.exe /clearfreebusy.

    Accepted Solution

    Download MFCMapi Editor
    Shutdown outlook, and install tool

    Possible solution 1 (use MAPI Editor to delete reminder):
    Cause: this symptom will appear if Reminder Queue werent consistent in Reminder Table or appointment has been corrupted
    Important: Delete reminder by using MAPI Editor will also delete the item from calendar, please backup your calendar before doing this
    1. Set outlook open in online mode and close outlook
    2. Run MAPI Editor ->Session menu-> Logon and Display Store Table->choose your mail profile (this will not appear if you only have one profile)->Right-click the one that display name column shows Mailbox-your name->choose Open Store
    3. Now in the second window, expand Root-Mailbox->Double-click Reminders
    4. In the third window, find that recurring appointment by checking Subject and To column->Right-click the appointment->choose Delete Message->select
    Permanent Deletion in pop-up window
    5. Then start OL with cleanreminders <outlook.exe /cleanreminders>

    Possible solution 2:
    1. If solution 1 werent working, following solution 1 to step 3, when you located Reminders folder, Right-click it->choose Delete Folder->do not check Hard Deletion in confirm window, just click OK
    2. Close MAPI Editor and start outlook with cleanreminders <outlook.exe /cleanreminders>

    PS: If you didnt see item in MAPI Editor, try to use OWA to seek the appointment
