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 Im using Outlook 2. Windows XP. Yes, they are quite old, but as any user of Pro. Tools knows, you stick with a solid operating system that works well. 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 Outlooks advanced options, but many of them such as this one dont show up there. So this is what I had to do 1 Run regedit from Start Menu, choose Run and type regedit. Navigate your way to HKEYLOCALMACHINESOFTWAREMicrosoftOffice OutlookAddins. The little subfolders in Addins are Add ins that are installed. To disable a particular Add in, set its Load. Behavior key to 2 Hexadecimal. In my case Adobe. Contribute. Office. Plugin was the culprit. Made the change and hey presto, the problem was solved Sorry for the very dull geeky post Ill try not to do them in futureHope its useful for someone though.
