[SOLUTION] Outlook 2000 opens, then closes; won’t stay open!

/54 Comments/in , /by

My Outlook 2000 would not stay open today!  I would open it, but it would immediately disappear and close.  Each time I open it, it keeps closing. I found the reason, which is iTunes 10, and the solution which did work for me:

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

For those of you having difficulty finding the file, find a find to get to the C: drive.  For Windows XP, it is My Computer.  For Vista or Windows 7, look for “Computer”.  Once you find C: and double-click it, double-click the Program Files folder (for 32-bit systems), and so on, following the paths listed above.  Searching for the file will probably be tough to make work.

[UPDATE 10/1/10] I just updated to iTunes 10.0.1 and it happened all over again!  The fix worked again…

    Worked like a champ. Tried various fixes to include repairing/clean install and your fix was the cure. Thanks, Don

    I just tried a few things (like repairing office) and this is the only thing that worked. Apple stinks.

    Thanks again.

    and had a suspision it was after iTunes updated.
    Will go away and try the fix-fingers crossed

    Thank you so much. This was driving mr up the wall. How typical of Apple to assume that everyone can afford to update a programme that is working perfectly and only address new versions.

  18. Ren says:

    Thank you so much. I had this problem before with a different itunes version and despite my requests to my son not to upgrade he just did to 10. I thank you so much for this. I need access to my e-mail account.

  19. Cathy says:

    Andy, I appreciate this so much – I tried to download itunes and it started to make me crazy so I bailed – forgot all about it until today. Reinstalled office, etc. How very cool that you wrote this, thank you! I would have been thrashing around for weeks!

    This support issue was driving me insane!

    Finally found your solution, remoted in to the customer’s computer, changed the filename and boom Outlook opens!

    Thank you very much.

    That’s a bingo!

  22. Bob Forder says:

    This was great! Thank you as this was driving the user nuts and in a couple of seconds of searching and applying this fix… it now works.

    Thanks Again.

  25. Frank Cranmer says:

    Thanks much. Your solution was spot on. I will pass this on to a friend who is having the same problem. Thanks again…

  28. Bonnie says:

    I don’t know how you figured this out…but it worked for me too!!!! Thanks for sharing. iTunes is the most un-user friendly program I have ever encountered 🙁

    Thanks again!

  29. Tina says:

  36. David says:

    Tried all the other fixes, but nothing worked. Yours worked like a charm. How do you figure these problems out anyway? (Rhetorical question) – Not that I would understand it anyway. Thanks

  37. Zygmunt says:

    Another big Thank you,
    We need to make this appear in other forums so people can find it easier. Hope you don’t mind if I copy it around a bit, will give you the credits! Thanks again

  39. Chuck Griffin says:

    Thanks for the solution. I had this problem and couldn’t figure it out. I happened right after I was troubleshooting another issue and saw the itunes relationship and remembered I had just updated itunes.

    Thanks again.

  40. Henry D says:

    dude – how did you know this?? 4 hours of pain and suffering. I tried fixes, scans, repairs and on and on.

    I wish I found this site sooner!!

  42. Christine says:

    This worked for me, too! It’s such a simple fix after I’d tried many other suggestions.

    Thank you!

  43. Alyssa says:

    Thank you! I was lost without my calendar and restored it just in time to get to an appointment I had forgotten about.

  44. Tom says:

    I’m not very computer savvy. If I do a search for this file (OutlookChange etc) the search companion will locate it and list it. Can the file be opened from that source and simply be renamed there and be done?

    Thanks, Tom

  46. Linda says:

    Thank you so much. Would never have figured that out by myself. Worked fantastic, hardest thing was finding the file to rename.

  50. Marjorie says:

    From the bottom of my heart, I THANK YOU!!! I thought the problem was with my Outlook and tried every fix I could find. I had no clue that iTunes was the problem. Thank you SO SO much for such an easy fix. Bless you!! I’ve wasted so much time trying to get my Outlook to stay open.
