|Had exactly the same problem, having installed I-Tunes10 last night, and then Outlook not staying open. I have Office 2000 on my PC. Ellelle10 above posted a link to the solution, but thought I would reinforce it here, by posting Apple's response to the issue:|
iTunes will sync with Microsoft Outlook 2003, Microsoft Outlook 2007, or Microsoft Outlook 2010. If you use Microsoft Outlook 2000, you can resolve this issue by renaming the "OutlookChangeNotifierAddIn.dll" file. This file can be renamed however you choose, and is found in the following default location depending on your operating system:
* Windows XP, Windows Vista (32-bit) or Windows 7 (32-bit):
o C:\Program Files\Common Files\Apple\Mobile Device Support\OutlookChangeNotifierAddIn.dll
* Windows Vista (64-bit) or Windows 7 (64-bit):
o C:\Program Files (x86)\Common Files\Apple\Mobile Device Support\OutlookChangeNotifierAddIn.dll
If you install Microsoft Outlook 2003, Microsoft Outlook 2007, or Microsoft Outlook 2010 after renaming this file, you may need to reinstall iTunes 10 before being able to sync Contacts, Calendars, email account information, or Notes.
I renamed it OutlookChangeNotifierAddIn - problem file.dll
