How to clear Outlook 365 Mail Auto-Complete

I have tried all recommendations:

- File > Options > Mail > "Empty Auto-Complete List"

- Delete NR2 file: I don't have one

- Edit Registry: I don't have the key

 

It's a useful feature, but useless now as it's cluttered up with outdated emails.  Thanks.

    Type ahead cache is stored server side now with exchange online. I found this article to clear it however not sure if there is a newer one since but it should give you a place to start. https://gallery.technet.microsoft.com/office/How-to-reset-OWA-auto-5b2b3d3b

      Yes, I tried the "/Clean..." switch.  This is Outlook 365 on the desktop; Win 10 x64.  Will check that link.  Thanks.

        That script appears to remove individual email addresses from AutoComplete.  How do I remove ALL email addresses?

    To confirm, are you using Outlook on the Web, or Outlook desktop?

    Have you tried closing Outlook, then opening it again with the switch below?

     

    Outlook.exe /CleanAutoCompleteCache
