Issue: If multiple Exchange accounts are used in Outlook, a list of different
usernames are shown in the Microsoft Office Outlook Credentials drop down menu.

Method:

  • Click start/run
  • Type: control keymgr.dll
  • Press ENTER
  • You’ll be presented with a gui with the list of stored user names and passwords.
  • To delete a set of credentials, click the item and click [Remove]
  • To change a set of credentials, click the item and click [Properties]
  • To add a set of credentials (this is what we want to do so they show on the pull down), click [Add]
  • For the server prompt, enter the full name (in the format of servername.domain.local)
  • Enter the user name using the domain format: mydomainmyuser
  • Enter the password, if you want, but Outlook will continue to prompt for
    it and ignore your entry here.
  • Click [OK]
  • Click [Close]
  • If Outlooks is running, exit it and restart it

When you are prompted to “Connect to”, you should see the user on the pull down list!
