New Outlook autocompletes an address that is no longer in use and I can't seem to delete it

Topic says it all, really.

Client of mine has a new company and when I type the start of his name Outlook autocompletes for his old company even though it is no longer in my address book and his contact is updated with new information.

I seem to recall there used to be an "x" that would let me delete incorrect autocompletes, but I can't find anything and Copilot has no useful suggestions. 

The autocomplete comes up in both the web version of Outlook--I basically never use this--on my PC which I primarily use, and IOS.

    I've run into this before with the new Outlook. Usually, when the unwanted address appears in the autocomplete list, you can highlight it using the arrow keys and click the X next to the suggestion (or press Delete) to remove it. If that doesn't work, try removing the contact from your saved contacts and clearing any cached recipient suggestions in Outlook settings. Sometimes signing out and back into Outlook also refreshes the autocomplete list. If the issue persists, there are specialized Outlook management and mailbox tools that can help troubleshoot cached data and profile-related problems more thoroughly.
