iTunes, Outlook Change Notifier add-in interfering with Auto-Complete

Collapse this imageExpand this image
assets folding start collapsed
iTunes also installs an add-in called Outlook Change Notifier. If you have iTunes Version 10.0.0.22, it had several issues that caused Outlook to not shut down gracefully, causing AutoComplete to not work correctly. Updating your iTunes software to version 10.1.0.56 or newer will take care of the Outlook Change Notifier issue.

If you no longer use iTunes or want to manually disable the add-in:

  1. From within Outlook, click File > Options and select Add-Ins.
  2. At the bottom of the dialog press the button “Go…".
  3. Scroll down the list until you find “Outlook Change Notifier” and un-check it.
  4. Press OK to confirm and close the dialog.

More information

What is the difference between AutoComplete and Suggested Contacts

Outlook also adds a folder to Contacts labeled Suggested Contacts. Addresses get added to this folder as you send or reply to messages addressed to people who don’t exist in your Contacts folder. Outlook doesn't look in Suggested Contacts for names during the AutoComplete process. It only stores addresses that you might want to add to your Contacts. You can double-click an entry in Suggested Contacts and a Contact Form opens that allows you to save it to your Contacts Folder.

Import AutoComplete data from older versions of Outlook into Outlook 2010 (Video.)
