Delete an Autocomplete Address in Outlook

Overview

Even when selecting names directly from the global address list and the address shows correctly in the "To:" field/line, it still uses the outdated information from suggested contacts if it is present.

1. Open a new mail and begin to type the email you want deleted. Click the X in the yellow pop-up box that appears when typing it in.
   
   
2. If not fixed, search both the "Contacts" and "Suggested Contacts" folders for any instances of that person and delete their email addresses (even if it's the correct new one). Note that someone's old address may appear in several forms, not necessarily just under their actual name. For example, one may appear in someone's suggested contacts as sbennett@csulb.edu (with no name), sbennett@notesmail.csulb.edu (with or w/o name), and/or Shenandoah Bennett. For this reason it usually takes a fairly thorough search to find everything.
   
   
   
   
3. If still not fixed, restart Outlook.
4. If still not fixed, create a new Outlook profile. Contact your college or department technical coordinator for assistance with creating a new Outlook profile.
