MS Outlook 2k "cannot turn off reminder"

I work with office 2000. Windows 2000. About 1 month ago I got a new PDA and aside from the fact that all my appointments duplicate in calendar and to do... I have another issue. I have three old appts. that won't go away. They pop up a reminder and when I hit dismiss or snooze I get the following box reading "Cannot turn off the reminder. You may be reminded again. The end date you entered occurs before the start date." If I try to open the item to fix the date problem I get "Cannot open the item for this reminder, The end date you entered occurs before the start date". So every five minutes are so these three are popping up and I can't get rid of them. I've tried repair and I've uninstalled and reinstalled outlook, office and updated all the office updates from Microsofts website. Two of them are recurring so I went into recurrence and tried to get rid of them that way and it's not letting me delete anything. It's driving me crazy. Please help.
Thanks,

I am having the exact same problem. Any luck on the fix?

Restart Outlook with the '/cleanreminders' switch, the easiest way to do this is Start > Run and in the Run box enter:

 

Ok I tried the outlook /cleanreminders

And it did not work.

Maybe my problem is not exactly the same.

I am running windows XP home version and my exact error messages are

When the reminder comes up and I try to open it I get

"Cannot open the item for this reminder. The end date you entered occurs before the start date"

When I try to dismiss the reminder I get

"Cannot turn off the reminder. You may be reminded again. Could not complete the operation. One or more parameter values are not valid."

 

I finally paid Microsoft for the answer. Here it is:

S: (Subjective)
Past Reminders keep firing with below errors every time Outlook is opened.

while dismiss them- "Cannot turn off the reminder. You may be reminded again. the end date you entered occurs before the start date"

while try to open the related item- "Cannot open the item for this reminder. The end date occurs before the start date"

Ø Reopened Outlook and don't find the past Reminders firing again. The issue got resolved.


Good Luck!

 

This is the exact message I get everytime I open my Outlook(2003). I get all the previous meetings/ reminders/ tasks etc. They never go away but keep on adding. And when I try to select one and say delete I get the following message.

"Cannot turn off the reminder. You may be reminded again. Could not complete the operation. One or more parameter values are not valid"

This message was extremely helpful. Thanks a lot. It solved my problem. Appreciate !

 

I was having the identical issue with the calendar, but when I deleted all of the reminders, it also deleted all of my appointments going forward.

I found some of the appointments in the deleted folders box, but when I put them back, I started the getting the original message - "Cannot turn off the reminder..." again.

FYI. I was using outlook 1007 with exchange server, I don't know if that matters.

An immense pain.

 

This worked! I'm using Outlook 2007 on Vista and it still worked

The only difference was instead of:

4. Select Mailbox

I had to Select - MDB, then "Open default message store".

Thanks!

 

I am experiencing the same problem; however, when I go to right click "Delete" I get the following two error messages:

Error:
Code: MAPI_E_CORRUPT_STORE == 0x80040600
Function lpSourceFolder->CopyMessages( lpEIDs, NULL, lpWasteFolder, NULL, NULL, MESSAGE_MOVE|MESSAGE_DIALOG)
File E:\MFCMAPI\5.0.18\MAPIFunctions.cpp
Line 1046

Error:
Code: MAPI_E_CORRUPT_STORE == 0x80040600
Function DeleteToDeletedItems( lpMDB, (LPMAPIFOLDER) m_lpContainer, lpEIDs)
File E:\MFCMAPI\5.0.18\FolderDlg.cpp
Line 595

Does anyone have a solution?

 

By the way, when I go to dismiss, amend or delete any reminder I get the following message:

"Cannot turn off the reminder. You may be reminded again. Could not complete the operation. One or more parameter values are not valid".

 

The problem appears to be getting worse as now I cannot open up my Contacts. I receive an error message that states:

"Can't open this item. Errors have been detected in the file C:\Documents and Settings etc. Quit Outlook and all mail-enabled applications, and then use the Inbox repair tool (Scanpst.exe) to diagnose and repair errors in the file. For more information about the Inbox repair tool, see Help."

I've tried the repair tool, including placing my CD-ROM containing my Office 2003 Edition, but receive an error message there too which states that I have an outdated version(?).

Regarding the Scanpst.exe, I try to launch that application but receive the following error message:

"Windows cannot find 'Scanpst.exe'. Make sure you typed the name correctly and then try again."

I tried searching for 'Scanpst.exe' on my computer using the search tool and finally located it but when it asked what file to open you can imagine my suprise that I have no "Local Settings" folder in my Documents and Settings folder.

Does anyone know what might going on?

 

I was also suffering from the dreaded "could not save item. could not complete the operation. one or more parameter values no valid" problem - but my issue stemmed from a task imported from my iPhone. The MFGMAPI solution reported back in December 2004 did work for me, except that I selected Personal Folders, then Tasks, THEN I selected reminders, right clicked to "Open Contents Table" and found my rogue reminder with an error code. Deleted it, and haven't been bothered since.

Fourteen weeks of constant reminders was driving me up the wall. I am DELIGHTED that this has been fixed.

Oh, and BTW - I am using XP with SP2 installed, and Outlook 2003.

 

I had the exact problem that you describe. I kept receiving the same 10 reminders and could not even delete them via the MfcMapi tool. I kept getting similar errors to yours. I actually experienced the same reminder issue twice. The first time I was able to use the MfcMapi tool however that deleted most of my calendar entries entirely, DOH!!!

I was finally able to resolve the problem the 2nd time by deleting my .ost file that contained my offline email/calendar data. The file was recreated from scratch after I deleted it and then my pesky reminders were gone. You can find your .ost location by going in to Outlook Tools/Account Settings/Data Files.

 

This appears to have fixed my problem in Outlook 2007. Thanks!

 

I have the same issue described in this thread, however my problem is that these fixes will not work for me.
I keep receiving the same reminders everytime I open outlook 2007 and can't delete them using the MfcMapi tool. The tool shows the problem entries and their detail shows multiple errors. I can't delete the enrty or it's detail.
If I open calendar in Outlook and go to view/current view/active appointment, they do not show there, nor do they display on the calendar itself.
I have tried everying including scanpst and cleanreminders and any other suggestions on various forums but with no luck.
I really don't know what to do now, all current resolutions appear to have been found with the MfcMapi tool.
I would appreciate any help.
I'm using Vista Ultimate SP3 with Microsoft Office 2007. All up to date.
