“Could not complete the operation. One or more parameter values are not valid.”

Just a quick (and very geeky) post in case anyone else ever has this problem with Outlook, because it was driving me mad for about an hour.

Basically the error message in the title would pop up whenever I closed Outlook, but only if I had opened or edited a note at some point. I should point out I’m using Outlook 2003 and Windows XP. Yes, they are quite old(!), but as any user of ProTools knows, you stick with a solid operating system that works well.

1st stop was of course googling the problem and lots of fixes are suggested including creating new data files, deleting some outlook system files, turning off dates/times for notes, and turning off task filters. None of these were any good for me.

Finally found a solution though. The problem was an add-in installed by Adobe Contribute (part of the Adobe Creative Suite I use). You can turn off some add-ins from Outlook’s ‘advanced options’, but many of them (such as this one) don’t show up there. So this is what I had to do:

1) Run regedit (from Start Menu, choose ‘Run…’ and type ‘regedit’).
2) Navigate your way to “HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\ Outlook\Addins”.
3) The little subfolders in ‘Addins’ are Add-ins that are installed. To disable a particular Add-in, set its “LoadBehavior” key to 2 (Hexadecimal).

In my case ‘Adobe.Contribute.OfficePlugin’ was the culprit. Made the change and hey presto, the problem was solved!

Sorry for the very dull geeky post – I’ll try not to do them in future!!! Hope it’s useful for someone though.

    I had the same issue, I did it simple way.
    Just clear Auto-complete list from outlook advanced option , under mail tab.
    It’s working fine for me.

    Hey dude,

    It’s not geeky post at all. Very handy as a matter of fact.

    Thanks for sharing.
